material-components-web-react: Error importing scss instead of css

Hello,

I try to use the example given by moog16 here (issue #557 ) But I have this error :

@import "@material/drawer/mdc-drawer";
^
      File to import not found or unreadable: @material/drawer/mdc-drawer.
      in /Users/john/Desktop/app/node_modules/@material/react-drawer/index.scss (line 23, column 1)

Using CSS instead works fine
