Steps to reproduce

1. I tried to apply style on a v-html element
2. I followed the guide to add configuration to webpack so I can use deep selector >>> https://vue-loader.vuejs.org/guide/#vue-cli
3. Trying to rerun the development server
4. Error :

$ vue-cli-service serve --open --mode development --port 3000 --dashboard
 INFO  Starting development server...

 ERROR  Error: [VueLoaderPlugin Error] No matching use for vue-loader is found.
Make sure the rule matching .vue files include vue-loader in its use.

What is expected?

Server runs and I can use >>> deep selector

What is actually happening?

Server can't run and is throwing an error even if I'm following exactly the official guides to implement the vue-loader

You don't need to add vue-loader to vue-cli, it's already there and deep selector is working out of the box :)
