React modules installation fails - javascript

I'm trying to install sass-loader and node-sass via both yarn and npm , but getting the same errors .
I tried using one of these:
yarn add sass-loader#6.0.6 node-sass#4.5.3
npm install sass-loader#6.0.6 node-sass#4.5.3
But both produce similar errors. This is the response from yarn :
EDIT: I'm using windows. After setting the path of python this is the response I get:

I've tried downloading python 2.7 as stated in one of the errors. But the errors remains the same. I am stuck on this for 3 hours and would appreciate some help.
Could it be some permissions stuff? I don't understand why this is happening as I'm simply following a basic tutorial step by step .


It is a quite a common case that node-gyp build fails on windows.
to make the build pass, follow the steps described in the official documentation
The easiest way to make this work is by installing windows-build-tools using npm or yarn
npm install --global --production windows-build-tools
then try again to install node-sass and sass-loader
The problem can be solved too by using Bash on Ubuntu on windows


I think the error clearly states that python is not added in your environment variables or it is not even installed on the system. please resolve the python dependency and try again.

I cannot run any project because of gyp error. How can I fix this: npm ERR! gyp verb cli

Whenever I run my code I always get the same error. I uninstall node and npm and reinstall. But now there is no "node_modules" and I get the same error. How can I fix it?

There isn't node-sass and node-gyp. When I tried to install them I also got the same error. I cannot install anything.

I solved this problem by changing the node version to 14.15.1

Do not use node-sass anymore. Remove 'node-sass' in package.json. pls use 'dart-sass'.
https://www.npmjs.com/package/dart-sass (dart-sass is default now)

Please don't waste your time running the suggested command by others.
Please uninstall node.js and use the Node v14.x.
It will solve it automatically.

I got the same error and did this:
1. npm install node-sass
2. npm install
3. npm ci
4. ng serve --open (to launch the project ).

With most of the operating systems removing python2 this is a common issue for most projects. It definitely affected 4/5 of my recent projects after upgrading to current Linux/Debian Stable which removed python2.
The solution is for system to start using python3 and in order to do that you need to..
Solution/Solved is:
node-sass is actually at fault. Python2 is required until version 6.0.0. Normally you would upgrade to latest 7.0.3 but node-sass is currently obsolete, so we will swap to sass project.
yarn remove node-sass
yarn add sass
I've given more details on reasoning why here, or alternative dart-sass if you use "render() and renderSync() functions".:
Solved-ERR!gyp-info-using-node-gyp-3.8.0-gyp-verb-which-failed-Error-not-found-python2
Affected:
node.js /react web apps
Elixir/Phoenix assets
Android apps
Vue.js projects

The following solution works for me.
Try:
npm cache clean --force
npm uninstall node-sass
Uninstall node modules from your project
npm i sass --save

!important
i run into the same issue. ANd What I recomend to you is to install nvm to control your node version instead of unistalling the current version causing other problems with the existent projects.
NVM Installation Guide
https://www.geeksforgeeks.org/how-to-install-and-use-nvm-on-windows/
or
https://tecadmin.net/install-nvm-macos-with-homebrew/
After installation
After you are sure that you'd installed nvm successfully you can do:
nvm --version to check if nvm is successfully installed
nvm install [desired node version] ex.: nvm install 14.0.0
nvm list to check all node versions installed
nvm use [desired version] to change between node version ex.: nvm use 14.0.0
Conclusion
As I mention above, instead of unistalling your node versions you can install different versions of node and changing between then avoid future errors.

Getting node-gyp and node-sass error in Ubuntu OS

How to solve this issue in Ubuntu OS 20.04. I found some related stuff to solve it but all is related to window OS.

It looks like the error is saying that python2 is required to install this package, though I'm not sure why a node module should require python2 in 2021.
Just install python2 using the standard way to install on your machine.
For example, on Ubuntu, you might install via Terminal with:
sudo apt install python2

Everytime I Try To Run NPM Install Terminal throws several errors

This is on my work laptop. I have Latest version of angular, Nodejs, Nodesass, VScode and mentioned them in Local environment path as well. If I download any Angular template from Github and Try to do NPM Install and it throws these error always. What shall I do to fix these error?

I think you are using Windows for development. Some node.js modules required to build locally on a machine. so, that why it needs python version 2.x and other tools.
windows-build-tools package install required tools to build module locally. Go ahead and install this package and after installing it then try again running the command npm install command

gulp-sass error when installing

I have an error that gets thrown only when I try to install gulp-sass. I have tried installing other modules, (like gulp-livereload) and they work fine. Using npm version 6.0.0. Here is the package.json section that is requiring it:
"devDependencies": {
"gulp": "^3.9.0",
"gulp-autoprefixer": "^3.0.2",
"gulp-imagemin": "^2.3.0",
"gulp-livereload": "^3.8.0",
"gulp-sass": "^3.0.0",
"gulp-sourcemaps": "^1.5.2",
"gulp-uglifyjs": "^0.6.2",
"imagemin-pngquant": "^4.2.0"
}
The only one here that throws errors is gulp-sass. This is the error:

Turns out this wasn't a permission problem. All I had to do was add the flag --unsafe-perm=true. I suppose it is a problem with the gulp-sass postinstaller itself, judging from this github post. Thanks vishwa for pointing out the permission denied error, I would have never found that post without it. ;)

Based on that, I assume it require IP2Location library installed. I get the library from this
http://www.ip2location.com/developers/c and compiled that library using provided manual.
Then I downloaded the IP2Location source code, edit the binding.gyp to

'target_name': 'ip2locationnode',
'sources': [ 'src/ip2locationnode.cc' ],

I am not using IP2Location nodejs package since I'm dealing with legacy code. Rewriting it would require some effort compared to installing and configuring the addon. I don't have any issue compiling it in linux based package, but since the developer machine is Mac OSX Mavericks, it severely limit what I can do with it.

Have you tried this one instead?
The IP2Location one is actually https://npmjs.org/package/ip2location-nodejs
