Steps to reproduce

Create a new project using vue-cli@next.
In the preset, select TypeScript and Eslint Prettier.
Start a lint: the warning appears every time.

What is expected?

Eslint should be the latest version to support the most up-to-date version of typescript. The warning about typescript version should not be displayed

What is actually happening?

The following message is displayed:

=============

WARNING: You are currently running a version of TypeScript which is not officially supported by typescript-estree.

You may find that it works just fine, or you may not.

SUPPORTED TYPESCRIPT VERSIONS: >=3.2.1 <3.6.0

YOUR TYPESCRIPT VERSION: 3.6.4

Please only submit bug reports when using the officially supported version.

=============

---

This bug occurs with both vue-cli 3 and 4 (rc 8) on every new projects I created (giving that TypeScript and Eslint are enabled).

👍 just released v4 still has this old dependency / same issue

[sodatea]

Working on that. typescript-eslint/typescript-eslint#883
We've temporarily pinned the typescript version in the default generator to ~3.5.3 until that issue resolves.

[Mister-Hope]

Update a new discovery here with typescript-eslint. if you don't have a vue.config.js or an empty one, no errors when hot load triigered by file save.

But it you add chainWebapck options (even an empty one):

module.exports = {
  chainWebpack(config) { }
};

Errors like Here will disappear
@sodatea

If you think it's a new bug, I can open a issue.

[doits]

typescript-eslint/typescript-eslint#883 was closed/fixed in the meantime - does it mean this one could be fixed now, too?

[GauthierPLM]

@doits the error is still here and no update has been released yet. So I guess it's a bit early to close the issue without confirmation from the dev team that it's indeed fixed.

[doits]

@GauthierPLM What I meant to say is: Now that typescript-eslint/typescript-eslint#883 issue is fixed - which was a blocker for this issue here - can this issue be worked on and get fixed? Maybe by simply updating the deps?

[furudean]

Made a PR for this vuejs/eslint-config-typescript#4

Hopefully we can line up a release for this soon so we can close this!

[furudean]

eslint-config-typescript was updated to 5.0.0 so I think this issue can be closed
