ViewsError: 'node-sass' version 5.0.0 is incompatible with ^4.0.0
I've created a blank React project, using the command: npx create-react-app on npm v7.0.7 and Node.js v15.0.1
Installed:
- React v17.0.1,
- node-sass v5.0.0,
Then I tried to import a blank .scss file to the App component:
File App.js
import './App.scss'
function App() {
return (
<div className="App">
App
</div>
);
}
export default App;
It throws an error:
Failed to compile.
./src/App.scss (./node_modules/css-loader/dist/cjs.js??ref--5-oneOf-6-1!./node_modules/postcss-loader/src??postcss!./node_modules/resolve-url-loader??ref--5-oneOf-6-3!./node_modules/s

TL;DR
npm uninstall node-sassnpm install sass
Or, if using Yarn
yarn remove node-sassyarn add sass
Edit3: yes, another edit. Moving to sass (dart-sass) is the best solution. Previous one included locking node-sass to version 4.x.x, which is 2 years old and lacks newer SCSS features.
Edit2: sass-loader v10.0.5 fixes it. The problem is you might not be using it as a project dependency, but more as a dependency of your dependencies. CRA uses a fixed version, angular-cli locks to node-sass v4, and so on.
The recommendation for now is: if you're installing just node-sass, check the below workaround (and the note). If you're working on a blank project and you can manage your Webpack configuration (not using CRA or a CLI to scaffold your project), install the latest sass-loader.
Edit: this error comes from sass-loader. There is a semantic versioning mismatch since node-sass @latest is v5.0.0 and sass-loader expects ^4.0.0.
There is an open issue on their repository with an associated fix that needs to be reviewed. Until then, refer to the solution below.
Workaround: don't install node-sass 5.0.0 yet (the major version was just bumped).
Uninstall node-sass
npm uninstall node-sass
Then install the latest version (before 5.0)
npm install node-sass@4.14.1
Note: LibSass (hence node-sass as well) is deprecated and dart-sass is the recommended implementation. You can use sass instead, which is a Node.js distribution of dart-sass compiled to pure JavaScript.

The only one reason why you get some error like that, is because your Node.js version is not compatible with your node-sass version.
So, make sure to checkout the documentation at node-sass.
Or this image below will be help you in deciding what Node.js version can use the node-sass version.
For an example, if you're using Node.js version 12 on your Windows system ("maybe"), then you should have to install the node-sass version 4.12.
npm install node-sass@4.12
Yeah, like that. So now you only need to install the node-sass version recommended by the node-sass team with Node.js version installed on your computer.
