Try doing so, it worked from. You need to remove it from package.json with one the blocks below.

  If you are using npm and that node-sass is in your dependencies  :

npm uninstall node-sass --save npm install node-sass --save 

If you are using npm and that node-sass is in your devDependencies :

npm uninstall node-sass --save-dev npm install node-sass --save-dev 

If you are using yarn and that node-sass is in your dependencies :

yarn remove node-sass --save yarn add node-sass --save 

If you are using yarn and that node-sass is in your devDependencies  :

yarn remove node-sass --save-dev yarn add node-sass --save-dev 

First solution

Make sure your node.js version is not superior to the recommended one. If not, downgrade it, and for that, you could use n package from npm:

npm install -g n n stable # If one of the commands does not pass, you may need to use sudo sudo npm install -g n sudo n stable 

Then you would wanna use sass package instead of node-sass, as it's deprecated. And for that, run those commands:

npm uninstall node-sass --save npm install sass --save 

Second solution

If you need or want node-sass for some reason, you should downgrade your nodejs version to like v14. For that you can use n package from npm:

npm install -g n n 14 # If one of the commands does not pass, you may need to use sudo sudo npm install -g n sudo n 14
