Prettier v2.0.5 breaks linting

[jonahsnider]

Nearly identical stacktrace to #441. Makes me think something is wrong in how XO uses Prettier.

Are you using the latest XO version? XO only recently (e05efc3) received support for Prettier 2.

[jonahsnider]

I am using the latest XO version. Prettier 2.0.4 works fine with XO.

[sindresorhus]

I've locked Prettier at 2.0.4 until we can resolve this: https://github.com/xojs/xo/releases/tag/v0.30.0

[BarryThePenguin]

It's unfortunate as there are fixes for using prettier in editor plugins, including atom-linter-xo, in prettier 2.0.5

prettier/prettier#8047

Are they related at all?

[puka-tchou]

We're on prettier v2.1.1 and I've got the exact same problem. Is thers any fix coming?

As a temporary workaround, you can add eslint-plugin-prettier to your dependencies and use the latest version of prettier.

[jonahsnider]

This is almost certainly the same root cause as why having a different Prettier version breaks. However XO is importing or using other modules isn't resilient to version changes and seems to force you to use whatever version is specified in the XO package.json.

Same issue with XO having different version than you. #483

@sindresorhus I believe this issue shouldn't have been closed. PR #505 contained the sentence doesn't fix #466 but GitHub looked at fix #466 and went out to close this.
