node_modules does not seem to be an included path for Sass in CRA 2.0

Created by: jimbojetlag

I am not sure if this is a bug, or a feature. Apparently, node_modules/ directory is not an included path for Sass in CRA 2.0.

As instructed in #2859 (closed), node_modules/ prefix should be used when importing sass files from libraries. Including this prefix is not conventional in sass projects.

But then, even when using that prefix, libraries that import sass files other libraries will cause the File to import not found or unreadable error.

As an example, using @material/react-top-app-bar:

import 'node_modules/@material/react-top-app-bar/index.scss';

gives the error:

File to import not found or unreadable: @material/top-app-bar/mdc-top-app-bar.
      in node_modules/@material/react-top-app-bar/index.scss (line 1, column 1)
