What I did:

I use prettier-eslint via Vetur in VS Code and it's been working just fine up until today, when it started throwing the following error.

What happened:

[INFO - 8:33:35 AM] Loaded module 'prettier-eslint@undefined' from '/Users/daniel/code/ironmarch/web/node_modules/prettier-eslint/dist/index.js'.

Problem description:

Cannot find module './utils/ast-utils'

Suggested solution:

¯\_(ツ)_/¯

[skube]

I have a similar issue — but with react-hooks — which also just recently started acting up and not formatting anything anymore:

[INFO - 11:13:13 AM] Loaded module 'prettier-eslint@undefined' from '/Users/skube/client-app/node_modules/prettier-eslint/dist/index.js'.
[ERROR - 11:13:13 AM] Error
Failed to load plugin 'react-hooks' declared in 'CLIOptions': 
Cannot find module 'eslint-plugin-react-hooks'

node: v10.15.3
yarn: 1.19.1
prettier-eslint: 9.0.0

I'm wondering if this PR will fix things: https://github.com/prettier/prettier-eslint/pull/242

[zimme]

Please test with 9.0.1 and see if this is still a problem.

[selfagency]

Thanks, is it published on npm? Because I'm still getting 9.0.0.

[zimme]

@selfagency Yeah, should be published to npm, https://www.npmjs.com/package/prettier-eslint

Sadly no improvement

This _didn't_ fix my issue :(
https://www.stephencharlesweiss.com/2019-10-14/eslint-prettier-vscode/

However, the following steps did _seem_ to rectify the issue:

1. rm -rf ./node_modules && yarn
2. Add "prettier-eslint.eslintIntegration": true, to VSCode Settings file
   (ignore _Unknown configuration setting_ warning)
3. Reload VSCode window (⌘ R)
4. Remove "prettier-eslint.eslintIntegration": true, that was just put in
5. Try saving a file

¯\_(ツ)_/¯

Problem still prevails with newest version of VS Code. Tried reinstalling everything and while trying to format JS file this happens:

Why it is closed? Still not working!

I got the same issue, but i think mostly because the newest version of eslint.

[noisy]

@victoriatomzik just started getting this error too. Maybe this is something new? Like, package become broken

[EricRabil]

I believe @victoriatomzik's issue was related to typescript-eslint not supporting ESLint 5. https://github.com/typescript-eslint/typescript-eslint/pull/2917 was recently merged which fixes this.

This PR is available on NPM at/above 4.12.1-alpha.1
