touch .gitignore not creating file - reactjs

I'm trying to set up a React dev environment, and one instruction I've been given is to enter my directory in Terminal and type this code:
touch .gitignore
The touch command works fine when I'm making a file with a name and extension (e.g. index.html) but since this appears to be only an extension, nothing is happening.
Apparently it's an important file regarding uploading to GitHub - can anyone help?
Update: I created x.gitignore, and then tried deleting the x, and it OSX throws up a dialog saying:
You can’t use a name that begins with a dot “.”, because these names are reserved for the system. Please choose another name.

You can see all of the visible files within a folder by typing
ls
into your terminal (assuming OSX from your comment). However, you will only see a list of the non-hidden files. You can see all files by typing
ls -a
Your .gitignore file basically tells git which folders and files to disregard when packaging everything up to be stored. For example, in ReactJS projects you are probably going to be using a lot of NPM packages and you wouldn't want to include them in your git repository. So, in your .gitignore file, you would include a line that says
node_modules
and then none of the files or folders within node_modules would be included when you push to Github (or Bitbucket or wherever).
If you are having trouble finding the .gitignore file, first run the ls -a and make sure that you see the file listed. After that, if you are having trouble seeing the file in your text editor, you may want to check the preferences in the text editor.
In Atom, you need to unselect "View VCS Ignored Paths" to see the "ignored" files.

type in terminal
npx touch .gitignore

The file is not displayed in the editor because it is either binary or uses an unsupported text encoding

Is it related or not I don't know but when I install firebase and open VS Code again, this problem appeared in package.json and package-lock.json when click to 'Open anyway' button Text-Editor this nulnulnul issue come up

I deleted package.json files and install all packages again and it works
just extract the files before you even open the zipped files in the vs code
Had similar experience and these are the steps I took.
If you've push the project to github or any source control system, copy the package.json file in the repo, delete the corrupted package.json file in the project folder, then paste the copied package.json file on your project folder.
I went through this problem
The cause of the problem was that I had the files in extension Example.rar
Then instead of extracting the files by decompressing them
I dragged it through a program window through
instead of extracting it naturally
I was using a system at the time ubuntu And I want to access the files through a program "vs code"
The program I was using is called "Archive Manager"
The Archive Manager in Ubuntu is a utility program that allows users to manage compressed archives, such as ZIP, TAR, RAR, GZIP, and BZIP
Solve the problem if you go through the same experience as me
Unzip the files normally
Then try to make sure the files are working

Are github.com repository urls pointing to a folder or a file?

is this URL pointing to a .git file, or is it a folder path? In other words, is /redditclone.git a folder path or a file? The .git portion is throwing me off.
https://github.com/salvatoreallegra/redditclone.git
Thanks.
The .git is optional and still reference to a folder on GitHub side (it will be just redditclone if cloned on your side)
On GitHub side, those repositories are bare repos (meaning without working tree, just the Git data content), and by convention, a bare repo is designated by a .git extension (even thoug it is a folder)
This is a folder, the same way as explained on setting up the server:
https://git-scm.com/book/en/v2/Git-on-the-Server-Setting-Up-the-Server
$ cd /srv/git
$ mkdir project.git
this is standard made since the "long ago" times when there were many version control systems used at the same time by the companies and this suffix was meant to distinguish one from another. GitHub decided to adopt that.

JFreecharts Demo Code does not build?

I purchased the Docs/support from ObjectRefinery for JFreeCharts. When running ant the following occurs:
$ cd ant && ant
BUILD FAILED
/shared/jfreechart-1.0.19-demo/ant/build.xml:66: Warning: Could not find file
/shared/jfreechart-1.0.19-demo/source/demo/orsoncharts/iStock_000003105870Small.jpg to copy.
Actually that file does not exist anywhere in the project -or any jpg for that matter:
freechart-1.0.19-demo $find . -name \*.jpg
<no results>
So how to build this demo code?
There are two files missing from the ZIP file which prevent the demo jar files from being rebuilt using the included Ant script. This has been corrected and a new ZIP file uploaded to our server. Additionally, your purchase has been refunded.
Orsoncharts
is pervasive and broken within the build.xml and within the source code . The way to handle this is to:
remove the couple dozen or so references to orsoncharts from that build file
remove orson java sources
remove references and usages of orson from demo/SuperDemo.java
and then do
ant -f ant/build.xml all
Guess what? That is not enough. Now we get a supposedly unlicensed distro.
So we still can not work with the source code. This whole ant-based mashup is a broken hack.
At this point the answer would be "Will the distributors put together a real buildable source distro (without Orson Charts) or not."

How to upload an artifact to Artifactory / consume it in a build system (Gradle Maven Ant) where the artifact does not have an extension

I have the following files which I would like to upload to Artifactory as a 9.8.0 versioned artifact.
NOTE: The first two files DO NOT have an extension (they are executable files i.e. if you open them/cat on it, you'll see junk characters).
Folder/files of a given version 9.8.0 in CVS is like:
com.company.project/gigaproject/v9.8.0/linux/gigainstall
com.company.project/gigaproject/v9.8.0/solaris/gigainstall
com.company.project/gigaproject/v9.8.0/win32/gigainstall.exe
com.company.project/gigaproject/v9.8.0/gigafile.dtd
com.company.project/gigaproject/v9.8.0/gigaanotherfile.dtd
com.company.project/gigaproject/v9.8.0/giga.jar
com.company.project/gigaproject/v9.8.0/giga.war
Uploading the above files which have an extension is very easy... You log in to Artifactory as an administrator/user which has access to deploy artifacts, click on "Deploy" tab, browse for the Artifactory file and once you select the file, click on "Upload" button.
Next you'll see a screen (like shown above). You'll tweak what you want in the fields on this page and once you click on "Deploy Artifact", you are done. All you have to make sure is you select the correct file.extension file while uploading and make sure the file extension is shown in the "Target Path" box correctly (with the version -x.x.x, etc.).
My questions:
Question 1: How do I upload an artifact which doesn't have an extension? It seems like Artifactory by default takes an artifact as a .jar extension. How can I upload the "gigainstall" artifact as shown in the folder/file structure above for both Linux and Solaris? I see I can use the artifact name as gigainstall-linux and gigainstall-solaris and differentiate it, but I am not sure how to tell Artifactory that this artifact doesn't have any extension.
I don't think the development team will start generating this artifact with a proper extension (as this artifact may be hard coded everywhere in other projects where they are currently getting it from CVS/SVN source control somewhere - which is itself a bad practice to store an artifact in a source control version tool).
Question 2: How would I tell a build system (for example, Gradle) to consume a non-extensioned artifact during, let's say, 'compile' task. In build.gradle under section dependencies { .. }, I will add something like as shown below, but I am not sure for non-extensioned files (the first two in the folder/file structure I mentioned above).
dependencies {
//compile 'com.company.project:gigainstall-linux:9.8.0#'
//compile 'com.company.project:gigainstall-linux:9.8.0#??????'
//compile 'com.company.project:gigainstall-linux:9.8.0#""'
//compile 'com.company.project:gigainstall-linux:9.8.0#"none"'
//compile 'com.company.project:gigainstall-linux:9.8.0#"NULL_or_something"'
// The following will easily get giga.jar version giga-9.8.0.jar from Artifactory repository
compile 'com.company.project:giga:9.8.0'
// The following will easily get giga.war
compile 'com.company.project:giga:9.8.0#war'
// Similarly, other extension based artifacts can be fetched from Artifactory
compile 'com.company.project:gigafile:9.8.0#dtd'
compile 'com.company.project:gigaanotherfile:9.8.0#dtd'
}
Answer 1 (will cover 2 as well in a different sense): Using Artifactory "Artifact Bundle" feature section under "Deploy" tab can do the TRICK for AT LEAST uploading the artifacts in a way we want, by creating a zip file first (containing the structure and artifacts in it) --OR you can upload the artifacts using/calling Artifactory REST API way.
High level idea:
Create a zip file called gigaproject.zip OR anyname.zip/.tar/compressed file which Artifactory can read. Inside the zip, create the structure - how these artifacts will be loaded to Artifactory
i.e.
gigaproject.zip will contain the following folders/structure/files.
Case 1:
com/company/project/gigaproject/9.8.0/linux/gigainstall
com/company/project/gigaproject/9.8.0/solaris/gigainstall
com/company/project/gigaproject/9.8.0/win32/gigainstall.exe
com/company/project/gigaproject/9.8.0/gigafile.dtd
com/company/project/gigaproject/9.8.0/gigaanotherfile.dtd
com/company/project/gigaproject/9.8.0/giga.jar
com/company/project/gigaproject/9.8.0/giga.war
NOTE: In case 1 example, I didn't use any -x.x.x in the filename (i.e. I'm using plain and simple giga.jar instead of giga-9.8.0.jar).
The above Upload/Deploy will result the files (as shown in the following snapshot):
So, we have achieved what we wanted. Actually (visibly speaking yes), but not in a way Artifactory usually stores these artifacts (as they should -x.x.x version embedded in the file name and where artifact id should match the artifact filename). Now, if you want to consume the following in a Gradle build file, you CANNOT as first, you haven't uploaded the filename with -x.x.x version name in it, secondly, the artifact id in our case 1 tree was "gigaproject" (after com/company/project folder), so Gradle way of defining what artifact id and what artifact file name you want won't work.
compile 'com.company.project:gigaproject:CANNOTSAY_HOW_TO_GET_GIGA_JARorGIGAINSTALL_with_without_extension'
Conclusion: It's possible to upload any files (with/without extension in Artifactory) in any structure but it depends how your build system will consume it or will be able to consume it or not.
- I deleted the structure I just created with case 1 .zip file from Artifactory repository to try next case#2 and deleted the .zip file I created.
Case 2:
Let's create an individual versioned file name for each artifact and also create structure in the format - how Artifactory actually stores them (an artifact as seen in a repository in a tree view) and create a .zip file containing that structure. Let's use the same "Artifact Bundle" feature to upload this .zip file to upload individual artifacts that we need in Artifactory - where artifact-id (second value which we mention while trying to consume it) would match the artifactfile name in Artifactory.
Folder/file structure for the .zip file:
com/company/project/gigainstall/9.8.0/gigainstall-9.8.0.linux
com/company/project/gigainstall/9.8.0/gigainstall-9.8.0.solaris
com/company/project/gigainstall/9.8.0/gigainstall-9.8.0.exe
com/company/project/gigafile/9.8.0/gigafile-9.8.0.dtd
com/company/project/gigaanotherfile/9.8.0/gigaanotherfile-9.8.0.dtd
com/company/project/giga/9.8.0/giga-9.8.0.jar
com/company/project/giga/9.8.0/giga-9.8.0.war
NOTE: This time, we'll be using the same "Artifact Bundle" feature and for similar files (gigainstall under both Linux/Solaris folders), I took the approach of creating gigainstall folder (containing gigainstall-9.8.0.linux and gigainstall-9.8.0.solaris file names) i.e. when we'll consume these artifacts in Gradle under dependencies { ... } section for compile, we'll use x.x.x# way to fetch these artifacts from Artifactory.
OK, once "Artifact Bundle" Deploy/Upload was successfully complete, I got the following message.
Successfully deployed 7 artifacts from archive: gigaproject.zip (1 seconds).
Now, let's see how it looks like in Artifactory while searching for one of the artifact/in Tree view. You can see we have the files now in place, with filename-x.x.x.extension way so that I can consume them easily in Gradle.
In Gradle build file (build.gradle), I'll mention:
dependencies {
compile "com.company.project:gigainstall:9.8.0#linux"
compile "com.company.project:gigainstall:9.8.0#solaris"
compile "com.company.project:gigainstall:9.8.0#linux"
compile "com.company.project:giga:9.8.0
compile "com.company.project:giga:9.8.0#war
compile "com.company.project:gigafile:9.8.0#dtd
compile "com.company.project:gigaanotherfile:9.8.0#dtd
}
OH OH!! - That didn't work, see below for Gradle error. Why? - Artifactory Bundle upload/deploy feature uploads a zip file content what you have in the .zip but it DOES NOT create a .pom file per artifact it deploys. Thus, making the Gradle build to fail. May be in Ant this might succeed. This occurred for each individual .jar/.war/.dtd/etc file. I'm just showing one error example.
While doing gradle clean build
Could not resolve all dependencies for configuration ':compile'.
> Could not resolve com.company.project:gigafile:0.0.0.
Required by:
com.company.project:ABCProjectWhichConsumesGIGAProjectArtifacts:1.64.0

Case 3: Let's take a simple approach (workaround but will save a lot of pain).
Create gigaproject.zip file with the following structure, this approach takes - No x.x.x version value embedded in the individual artifact/filename in the folder/file structure. We will use "Single Artifact" approach (which will create the .pom for gigaproject.zip file automatically during the upload/deploy process provided by Artifactory). You'll still be able to get gigainstall file without needing any extension to its name using this approach. During the upload/deploy step, as you already have seen, you upload gigaproject.zip and artifactory will upload it to a given Target Repository as "gigaproject-x.x.x.zip" where x.x.x is 9.8.0 in our case. See the image snapshot below.
gigaproject/linux/gigainstall
gigaproject/solaris/gigainstall
gigaproject/win32/gigainstall.exe
gigaproject/gigafile.dtd
gigaproject/gigaanotherfile.dtd
gigaproject/gigaproject.zip
gigaproject/giga.jar
gigaproject/giga.war
Now, upload it in Artifactory using "Single Artifact" feature. Click "Deploy Artifact" once you tweak the values for GroupId, ArtifactId, Version, etc.
Once this is uploaded. You'll see in the zip artifact in the target repository (I took a bad example, usually this would be libs-snapshot-local or libs-release-local instead of ext-...), you'll be able to consume the ZIP artifact directly in Graddle:
dependencies {
// This is the only line we need now.
compile "com.company.project:gigaproject:9.8.0#zip"
}
Once the .zip is available to Gradle build system, now you can tell Gradle to unpack this .zip file somewhere in your build/workspace area where you can feed the actual(unpacked) files (gigainstall, .dtd, .jar, .war, etc.) to the build process/steps.
PS: Case# 1 and 2 would have worked for Ant I guess.
Answer 2:
If you have uploaded a non-extensioned file in either way. Make sure you have manually created/uploaded its POM file as well (i.e. if I uploaded gigainstall-9.8.0 as an artifact under com/company/project/gigainstall/9.8.0/gigainstall-9.8.0, then at the same level, I have to/should create it's POM file (see a simple template .pom file for a custom jar artifact or while uploading an extensioned file via "Single Artifact" deploy, you'll see what POM Editor window shows you) and upload both so that Gradle won't error out saying no POM conflict/error. Ant might not need pom (I didn't check that).
Once it's there in Artifactory, the following line should work -- OR comment please if you find another way.
dependencies {
// See nothing mentioned after - x.x.x#
compile "com.company.package:gigainstall:9.8.0#"
}

Install Packages (for dummies)

I know there's a lot of information on here about installing python packages, but I'm quite new to python and I think I need a more "for dummies" level of help.
I was trying to install openpyxl for which as far as I can tell I need easy_install, for which, as far as I can tell, I need setuptools. I tried running the code provided here https://pypi.python.org/pypi/setuptools which is supposed to download and install setuptools (and according to some sites, easy_install aswell?) - it runs successfully, but help(modules) doesn't show setuptools or easy_install as modules, I have no idea whats installed and what isn't, or how I'm supposed to install any of it!
Essentially I'm very confused, very frustrated and really need someone to talk me through (in idiot-speak) what I'm supposed to do.
Thankyou!
We all start somewhere, I was there two weeks ago.
I'll assume you're using Python2. I believe Distribute and Pip are recommended for Python3 (which I will be using as examples). I will also assume you are on Windows.
First, python needs to be registered to Path. To check if this has been done automatically, open a command prompt (start -> programs -> accessories), and type 'python', then enter. If it returns the version number, etc, skip down a bit. If it throws an error, you need to add Python to Path.
Adding Python to Path
To add Python to Path on a Windows computer, go to:
Control Panel -> System -> Advanced Settings -> Environment Settings -> System Variables
Scroll down to select path, then click edit. Copy the entire line to a text document, and add your install directory for Python.exe (and the scripts folder) using ';' as a delimiter between different directories. Copy this back to Path and save. (Additionally close your command prompt window to reset it.)
For my Windows 7 machine, I added:
;C:\Python33;C:\Python33\scripts;
Take care when editing this file. There are many videos out there describing this in detail if you feel unsure about changing this.
Installing Modules (Such as setup_tools)
Once Python is registered in the Path file, download and unzip setup_tools to a folder within your Python install directory called 'modules'. I use ExtractNow to unzip, as it will unzip twice (as required) automatically.
Open a command prompt window again, and direct it to change directories by typing
cd [directory for module you want to install]
On my computer, this would be
cd C:\Python33\modules\distribute-0.6.40
Again, I use distribute, rather than setup_tools as it sounds like you need would for Python2. Simply use the appropriate directory. Press enter to change the directory.
Once you've entered this and it shows a changed directory, type:
python setup.py install
This indicates that you want to use the program python to use the setup.py file in the specified folder to install the module. This should be successful, and will write many lines of code.
If you want to install other modules, you would install them in a similar way. Python would automatically use setup_tools on your computer to finish each install.
Remember to import at the start of your script when using them to code:
import [module]
Happy Programming!
