Error: Cannot find module 'typescript'

[Revadike]

@antfu sadly v0.5.3 brought this bug back.

Can you give a new reproduction? We didn't change much about that part

[Revadike]

IDK what changed, very odd, but now even v0.5.2 doesn't work anymore. It may be related to one of your dependencies? I believe it happened after doing yarn upgrade.

Here is the stack:

checking npm ls gives:

Seems to introduced by this line: https://github.com/un-ts/eslint-plugin-import-x/blob/34e1334a907d56150133bf338174a172ce89173d/src/utils/parse.ts#L3

Hmm, I checked their docs and it seems the difference between the plain js and ts version is the use of @typescript-eslint/parser. Are you using this? Always, or just with ts?

[antfu]

Always. Because it's about import and not TS specific. It's the side-effect they introduced.

[SukkaW]

Was bought to here by un-ts/eslint-plugin-import-x@ac11f62#r146221700

Is it possible that typescript-estree declares typescript as its peer dependency? But it is an optional peer dependency which should not cause any problem.

[SukkaW]

Might wanna raise the issue to typescript-eslint instead. It seems that importing withoutProjectParserOptions alone will also run loads of side effects that require typescript.

[antfu]

Importing the module (https://unpkg.com/browse/@typescript-eslint/[email protected]/dist/index.js) end up importing all the modules in typescript-estree, which end up with the side-effect that importing typescript - maybe they can do a pure submodule like @typescript-eslint/typescript-estree/withoutProjectParserOptions?

[Revadike]

🎉

[SukkaW]

@Revadike @antfu [email protected] is just released with the workaround included!

[Revadike]

A yarn upgrade did not fix it yet.
I think @antfu needs to update @nuxt/eslint first

[SukkaW]

A yarn upgrade did not fix it yet.

The [email protected] also includes a new feature, so it is a minor change, not a patch change. yarn upgrade might not perform a minor bump.

[Revadike]

Can confirm it's working now. Thanks again @SukkaW and @antfu!

[Revadike]

I don't know what happened, but the error is back again...

[Revadike]

I did a full clean install, but still getting this error

[antfu]

Please send a reproduction

[Revadike]

Please send a reproduction

Still same link:
https://github.com/Revadike/reproduction

[antfu]

You are not even upgraded to v0.5.6

[Revadike]

You are not even upgraded to v0.5.6

Check the yarn.lock file:

$ npm ls @nuxt/eslint
reproduction
└── @nuxt/[email protected]

[Revadike]

Somehow, even installing typescript does not fix it...

Any progress @antfu ?
Are you not able to reproduce it?

[Revadike]

@antfu please let me know if I can do anything to help

[SukkaW]

@antfu

I am not able to reproduce the issue using his reproduction with yarn 1.22.21. I suspect he doesn't delete the .nuxt folder and re-run the codegen or he doesn't use the yarn 1.22.21. I recommend locking the issue.

[Revadike]

@SukkaW hmm, you're right! I no longer have the issue with the updated version. I guess it got resolved on its own. If only everything could be that way.

[Revadike]

@antfu it's that time again to reopen this issue... why does it keep coming back?
