Node-sass does not run on npm-start V6.0.0

Question

I have been trying to install node-sass using

npm i node-sass

but I am getting the following error whenever I try npm start:

Node Sass version 6.0.0 is incompatible with ^4.0.0 || ^5.0.0.

I even tried downgrading to V5.0.0 or V4.14 for node-sass but it just won't install! It would get stuck at the end, and when I would force exit using ctrl+c, it outputs a huge log (please let me know if I can post it here).

Any help would be appreciated

Answer 1

I faced the same issue, I needed to check my node version by running node -v and compare to the supported node-sass version

Then I uninstall the node-sass with npm uninstall node-sass (I uninstall the @types/node-sass as well, check if you have devDependencies containing a reference to node-sass and remove it) and then reinstall again npm i [email protected] it was 4.14 in my case because I have NodeJS v14.16.1 installed, I runned npm i to rebuild all the packages I had and it fixed my problem.

Answer 2

This fixes it

To install a working node-sass version, you can use

npm uninstall node-sass
npm install [email protected]

Choose your version number using the following table, according to the node version you are using, which you can check using the command node --version

I hope this is helpful

That message is related to sass-loader that had a specific version range, that was expanded in https://github.com/webpack-contrib/sass-loader/releases/tag/v11.1.0
