I am using Spyder IDE and I want to istall pywin32. I tried:
pip install pywind32 !pip install pywind32' %pip install pywind32`. Nothing works and I keep receiving a 'invalid syntax' error.
Does anyone know what the syntax is to install packages on Spyder ?

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
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

I tried to install create react app using sudo npm install -g create-react-app on my terminal, then this message appeared:
/home/mahi/.npm-global/bin/create-react-app -> /home/mahi/.npm-global/lib/node_modules/create-react-app/index.js
+ create-react-app#1.4.3
updated 1 package in 11.7s
Then when I am going to run the command create-react-app hello-world, it says create-react-app command not found. Then I searched for many solutions, I tried almost all of them, but nothing improved, showing the command not found again and again.
I had this same problem and this is how I solved it.
It will work on Ubuntu 16.04 as well as Ubuntu 18.04.
First, open up terminal and run this command:
sudo npm install -g -y create-react-app
After that, you will be able to use the create-react-app anywhere on your machine because it is saved globally.
Are u sure to run npm install with sudo? I had same problem and terminal couldn't write to folder with commands. Does your /usr/local/lib/node_modules/ folder contains create-react-app?
are you using create-react-app with sudo? because if you installed the package using sudo npm install create-react-app then it is installed for this user, try sudo create-react-app and if it works then you should change ownership to your user
I use to have the same problem in the terminal when i write npm install -g create-react-app and them create-react-app my-first-app.
So i went react doc and i find npx create-react-app my-first-app that worked for me.
Hope that will help.
If you read carefully then you will see after installing Yarn it tells you to add the following thing in your path.
export PATH="$HOME/.yarn/bin:$HOME/.config/yarn/global/node_modules/.bin:$PATH"
~/.yarn/bin is for yarn binaries only.
Try it!

I need to setup the web server for Angular.js application using Nodejs. Accordingly I installed node.js version 6.11.0 in the path: C:\Program Files\nodejs
Next step is to install module of nodejs using the command:
npm install deployd -g
I am installing it in a path where my node_modules are installed.
When I run the command: npm install deployd –g I get one warning message (please see image for reference)
enter image description here
So I get to know that deployd is installed in the path C:\Program\node_modules\deployd.
Now if I run dpd –V command, it shows that dpd is not recognized as an internal or external command.
Can anybody please help me installing deployd?
I think this could help. It's worked for me.
npm install deployd-cli -g
Hey there!
So, I'm testing React-Native and this problem have come up, and not sure what it wants.
I have upgraded it, and also download latest versions.
This is the error:
npm WARN react-native-camera#0.6.0 requires a peer of react#>=15.4.0
but none was installed.
It won't allow me to download it running the following command
npm install react-native-camera --save
Thanks for your time.
Hey i had the same problem with react native camera
First make sure the version is up to date.Either latest or next. Unless update it
as
npm install npm#latest -g
Then reinstall camera again(No need to uninstall anything, because it is not installed yet)
Here is the same issue that i opened in github now Closed because it solved the problem :)
EDIT:
i'm sure you got this error when you start to run
npm install react-native-camera#https://github.com/lwansbrough/react-native-camera.git --save
command right ? so it failed and never installed so,
what you have to do is run command
npm install npm#latest -g
then run
npm install react-native-camera#https://github.com/lwansbrough/react-native-camera.git --save
back again
