As the error says Error: Cannot find module 'node-sass'. To solve this you have to install node-sass using following command:

npm install node-sass

In case someone's getting version incompatibility error after installation: Uninstall latest version: npm uninstall node-sass Then install desired version for ex: npm install [email protected]

The node-sass library is deprecated. Use sass instead:

npm install sass

Welcome to StackOverflow. You should add that the import/require statement has to change as well. Also, do you happen to know if breaking changes were introduced when they moved to the JS-only implementation? Then a link to an upgrade guide would be of immense help, too.

As per the error, the node-sass is not present or may be not installed properly.

You have to install using below command

npm install node-sass

or

npm install --save node-sass
