Pay attention to your terminal output, any rules that it can't match or if it needed to install any additional dependencies will be shown there. Agree with the other person about .scss requires a link! Let's take a look at the configuration that was generated from a new CLI project: Notice that most of the configuration is inside the overrides field. Having lint setup is useless if you have to run it manually every time before you make a commit. Do I need to change any eslint - typescript configuration in order to avoid this type of errors? I ended up doing two manual steps, as explained above: You could either do it manually by removing those from package.json, but remember to run another npm i to update your package-lock.json. And that's it, the migration should be over.
