pre-commit hook broken by recent eslint changes

[living180]

When developing against the main branch of DjDT, I can no longer commit changes to JS files due to a failure in pre-commit. If I force a pre-commit run on the tip of main without any changes, I get the following output:

% pre-commit run eslint --files debug_toolbar/static/debug_toolbar/js/toolbar.js
eslint...................................................................Failed
- hook id: eslint
- exit code: 2

Oops! Something went wrong! :(

ESLint: 9.0.0-beta.0

Error: Cannot find module '@eslint/js'

If I revert the recent eslint changes from 38d2eea5f8b57f70a4b5bdebd6bdeae8c395d822, pre-commit works without any problems.

I can't seem to reproduce this unfortunately. What version of node and npm are you using?

[living180]

I'm using the versions from the stable branch of Gentoo Linux:

% node --version
v20.11.0

% npm --version
10.2.4

Gentoo has multiple other versions of nodejs available that I could try if you think that would make a difference.

Something interesting for me. When I restarted my pre-commit environment I see this in my logs:

[INFO] Initializing environment for https://github.com/pre-commit/mirrors-eslint:eslint@v9.0.0-beta.1,@eslint/js@v9.0.0-beta.1,globals.

Maybe 9.0.0-beta.0 was yanked?

[tim-schilling]

Nope, it's still there.

[living180]

I downgraded to the oldest version of nodejs available in Gentoo:

% node --version
v18.17.1

% npm --version
9.6.7

then ran pre-commit clean and still had the same issue.

Perhaps merge #1900 to see if the release candidate fixes things?

• 1900

git commit --no-verify can be a workaround.
