**What source code are you linting?**

Various.

not relevant.



**What did you expect to happen?**



No warning to be issued by YARN because of the above.

The `eslint-config-prettier` should be part of `eslint-plugin-prettier` dependencies or peerDependencies. other package managers may not report such issue because they are not as strict in having dependencies being declared before being used.



**YARN version - IMPORTANT**

2.1.1



**What actually happened?**



```

(node:7832) [MODULE_NOT_FOUND] Error: eslint-plugin-prettier tried to access eslint-config-prettier, but it isn't 

declared in its dependencies; this makes the require call ambiguous and unsound.

```

then linting happens with no issue.
