Install NPM on linux - angularjs

My purpose is to install angularjs !
For that i need => npm,so I want to install nodejs for having "NPM" but i have this error :
File "./configure", line 16, in <module>
from gyp.common import GetFlavor
File "./tools/gyp/pylib/gyp/__init__.py", line 8, in <module>
import gyp.input
File "./tools/gyp/pylib/gyp/input.py", line 873
except ImportError as e:
Probably the problem is the version of python 2.5 : The problem is i don't have right to update python.
PLZ, how can i install npm on linux without Nodejs
Helps appreciated.
Regards

First update your system's package and make sure you have newest versions of packages and their dependencies.
sudo apt-get update
Then install npm(and/or nodejs if needed)
sudo apt-get install npm nodejs
Finally, you may install angular with following command
npm install angular
FYI, The best way to install npm is to install node using the node.js installer. npm is installed as part of node.

Error Trying to Install React on Windows 10

I'm trying to install react on windows 10 using npm install -g create-react-app.
The install fails and I get the following error message:
Error: EINVAL: invalid argument, mkdir 'C:\Program Files\Git\'C:\Users\User\AppData\Roaming\npm''
I should mention that I installed nodejs version 12.16.3 LTS on my windows machine right before I got this error.
Does anyone know why this is, or if there's a solution to this problem?
Please help!
First of all you are not trying to install react. You are trying to install create-react-app terminal tool. With that tool you can easily create react projects.
Let's do some checks first.
# Remove if you have installed it before
npm uninstall -g create-react-app
# Check if you have installed 'git' (if not install git)
git --version
# Check node.js (if not install node.js)
node --version
# Check npm (if not install npm)
npm --version
If they are all installed, now you can start installing create-react-app. I am not windows user but i would suggest you to use powershell. On linux i would use sudo command for this install.
# install create-react-app
npm install -g create-react-app
# check if it is installed
create-react-app --version

can't run npm install in laravel project how to fix it

I'm creating a laravel application with react template, when I run npm install
throws an error exception, I also tried changing folder permissions, removed
node_modules then reinstalled it but not working any solutions???
Judging by the error I see in your console:
pngquant failed to build, make sure that libpng-dev is installed
Seems like you don't have a pngquant package installed. Try the following steps:
Install package locally:
sudo apt-get install libpng-dev
Install npm package:
npm install -g pngquant-bin
If you already have node_modules directory in your project, delete it and install node_modules again:
npm install
According to Image Provided, Everything seems to be fine until it hits this missing package causing the exception to be thrown.
The missing package is libpng-dev: A virtual package.
See the Debian policy for a definition of virtual packages.
You can see here for details.
You have to Run this Command
sudo apt-get install libpng-dev
In case you hit an error saying it has been installed before, It means you have installed another build of this package. Hence, you have to reinstall it.
sudo apt-get install --reinstall libpng12-0=1.2.51-0ubuntu3
And then, try running npm install
I hope it works.
I solved similar issue in my localhost environment by moving libraries from devDependencies{} into dependencies{}
Otherwise
You should set global Node environment called NODE_ENV to development
NODE_ENV=development

ERROR in Cannot find module 'node-sass'

Config: macOS High Sierra, version 10.13.2, node:v8.1.2 npm:5.0.3
When I run npm start in my angularjs project I get this error:
ERROR in Cannot find module 'node-sass'
After this I run:
npm i node-sass
Now I get this error:
gyp: No Xcode or CLT version detected!
gyp ERR! configure error
gyp ERR! stack Error: `gyp` failed with exit code: 1
Why won't npm install node-sass? How can I install node-sass?
Here's the solution:
sudo npm install --save-dev --unsafe-perm node-sass
Enjoy!
Edited to explain the options (from comments):
--save-dev is used so that your app is able to find the module in local node_modules. --save-dev adds package to devDependencies in package.json. --unsafe--perm is used to run install scripts as root. To avoid sudo, use nvm instead. --unsafe--perm is really not needed as sudo is already mentioned. So the command basically air tights the script to install node-sass at any cost.
This error is for node-sass is not present ... to solve this just you want to run following command
npm install node-sass
According to node-sass github page, supported node.js version vary release by release.
https://github.com/sass/node-sass
Example:
Check the version of node you are running.
node -v
-> v12.0.0
you need node-sass v4.12+. so you can
npm install node-sass#4.12.0
or if 4.12.0 is the latest
npm install node-sass#latest
(npm install node-sass will install the latest version in many cases, but remember that it does not always install the latest(in this example 4.12.0) if dependency in package.json is written like ^3.0.0, ~4.11.0)
What's the difference between tilde(~) and caret(^) in package.json?
Lastly, using sudo with npm is not a good practice. Please refer to this article.

Doing npm uninstall node-sass and then npm i node-sass did not work for me.
Solution worked for me is npm install --save-dev node-sass.
Happy Coding..
Run:
npm rebuild node-sass --force
and it'll work fine.
It worked for me...
sudo npm rebuild node-sass --force
node-sass is not being installed and it can be one of many reasons
You have not installed it
npm install node-sass --save-dev
You are having a permissions error
sudo npm install --save-dev --unsafe-perm node-sass
You had a memory issue because it tried to make it (build from c code in your platform),this applies to some platforms and node versions
node --max_old_space_size=8000 $(which npm) install node-sass --save-dev
Your node and npm versions are not compatible,which most probably generated a failure in the build process,
In this case use n or nvm to make sure you have the same version in the new and original environment, the one where it did work, as this is usually by using different versions in different environments
This is what worked for me. I first uninstall node-sass. Then install it back.
npm uninstall node-sass
npm install --save-dev node-sass
It failed for me because I was using the latest version of node (12.7.0) I then had to explicitly install the latest version of node-sass with:
npm install node-sass#4.12.0
I have fix this problem without installing node-sass by this command:
npm install node-sass#4.12.0 --no-save --unsafe-perm
One of the cases is the post-install process fails. Right after node-sass is installed, the post-install script will be executed. It requires Python and a C++ builder for that process.
The log 'gyp: No Xcode or CLT version detected!' maybe because it couldn't find any C++ builder. So try installing Python and any C++ builder then put their directories in environment variables so that npm can find them. (I come from Windows)
I checked the Node version in my local machine, which is v10.11.0.
Then when I checked my development machine, where the error occurred, it had Node version V.10.8.0.
Upgrading Node to v10.11.0 in my development machine fixed the issue.
Hope this helps.
In my case I had to also had to perform:
npm install sass-loader
To fix the problem
There is an issue with downloading npm dependencies due to network which you have. try to download the npm dependencies in open network . you won't get any issue. i am also faced this similar issue and resolved finally.
use below commands: npm install (it will download all depedencies)
npm start to start the angular application
npm install node-sass will do the job in most of the cases, as it will add missing sass npm dependency module doesn't exist or it will overwrite previous crashed version.
For Mac Users use sudo in front of above commands.
On Windows machines npm rebuild node-sass --force may not work for some users because it's essentially saying, "please force npm to rebuild the sass node module for me". It will not work because that module doesn't exist.
Whenever you did npm install to the initial installation, the sass module did not get installed, which is why this problem occurs.
My problem was that a webfilter didn't allow me to download the node-sass package, when I executed the command
npm i
After the installation of the Windows Build Tools
npm i -g windows-build-tools
it build node-sass on it's own and now I can use it.
PS: I also installed Python 2.7.17 before, but I don't think that helped.
Try sudo npm install node-sass#4.12.0 if your node version is 12.
you must install node-sass in dev section of package.json
npm install --unsafe-perm node-sass --save-dev
If you run
npm install node-sass
and it still doesn't work remember to change permission to folder
I have also been facing this error. None of the above methods work for me. Please follow this as it worked for me.
For Installing node-sass in Ubuntu 16 via npm :-
You can install with npm 5.2.0 Version
If you are using nvm :-
nvm install 8.2.1
nvm use 8.2.1
npm install node-sass
If you are using npm separately then upgrade or downgrade npm version to 5.2.0
npm install node-sass
I ran into this error while I was using Microsoft Visual Studio Code's integrated git terminal. For some weird reason VS code was not allowing me to install 'node-sass'. Then I used 'Git Bash' (which was installed with git) and ran the following command:
npm install node-sass
It worked for me. I don't know why & how it worked. If anyone has any explanation please let me know.
You should try to check the log generated by npm install.
I have faced the same issues, and I found the error that python2 is not found in the path (environment variable).
After installing Python, everything worked fine.
I had a similar issue when I tried to run a project.
First i uninstalled the current version
npm uninstall node-sass
Then i reinstalled to the latest version with
npm install node-sass
Upgrading to latest version of nodeJS solved my problem
npm install --save-dev --unsafe-perm node-sass
This will do magic, you can use it with sudo
I had the same error when installing dependencies in Angular. I've tried aforementioned techniques but none of them worked until I've deleted package-lock.json which was previously created when running Node v11.
Now I'm using Node v12 so this is how I got resolved.
I repeat if you have package-lock.json delete it, file and then install dependencies.
Exactly same issue i was also facing and i tried all above answers but could not resolve, Below is the command which fixed my problem.
npm install sass-loader sass webpack --save-dev
https://www.npmjs.com/package/sass-loader
I've fixed this problem by installing v10.16.10 node version.
I met same issue installing node-sass when I am on Node 12.9.0
Once switching to Node 10.19.0, the issue is gone.
Reference: https://github.com/sass/node-sass/issues/2632
There seems to be an issue with the version "node-sass": "4.5.3", try updating to the latest version. Such as you could try adding ^ "node-sass": "^4.5.3" for the latest version
