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.

  • What does `which -a python2` show when you execute it in your terminal? – t.niese Mar 24 '22 at 08:24
  • nothing comes out ``` (base) MacBook-Pro:12-vue-spa bng$ which -a python2 (base) MacBook-Pro:12-vue-spa bng$ ``` – su-wan Kenobi Mar 24 '22 at 08:47
  • Ok so it looks like python2 is not installed or cannot be found, but whatever you want to install expects python2 to be installed. So you have to install it using e.g. brew. – t.niese Mar 24 '22 at 09:02

    In above comments, It is mentionded node 14 works, [you can downgrade 14 from here](https://stackoverflow.com/questions/47008159/how-to-downgrade-node-version#answer-61491579) – Ucdemir Oct 01 '22 at 10:11

    I tried node 18.x but i get the error. downgrading to 14.15.5 solved the issue for me. Ahsant Hamvatan. – afruzan Oct 06 '22 at 09:15

    NOTE: DOWNGRADING is not a good option! It's like suggesting to go with old version of software that is end of life. Please UPVOTE the answer with yarn remove node-sass yarn add sass. Don't compromise security of your program. – Lucas S. Jul 27 '23 at 13:23

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)

update answer at 2023/08/24

the answer still stand. we can see node-sass -> dart-sass -> sass.

now pls use sass https://www.npmjs.com/package/sass

    Indeed! Removing `node-sass` from package.json made `npm install` finish successfully, finally! – М.Б. Nov 12 '22 at 14:13

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.

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".:

Affected:

  • node.js /react web apps
  • Elixir/Phoenix assets
  • Android apps
  • Vue.js projects

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 ).

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

Please uninstall the nodejs and reinstall the node version 14.21.3

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:

  1. nvm --version to check if nvm is successfully installed
  2. nvm install [desired node version] ex.: nvm install 14.0.0
  3. nvm list to check all node versions installed
  4. 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.

Be Happy even with bugs
