Unable to run grunt-eslint with version 25.0.0 - "Could not find config file. Use --force to continue."

[codders]

Hi there,

I've just upgraded from v24.3.0 to v25.0.0 with npm i [email protected]. This pulls in the tgz from registry.npmjs.org (with hash sha512-JIV5IPgOuacorFLmYtUTq0n+0qGIL9FSQJ4KVnNfCg/8Fm+K1t6OWrzXXI8TxWTwq2K9E3parFVXCpn1sGLbKQ==), but that archive is only 2.5k zipped and contains just 4 files.

The file for download from the Github releases package is 50k zipped with a sha512sum of 591c37fccae5365d8e82d9738de855ce7ce2a60928802cdff46225b28727faca227245fdfb5fdc66ce9bf2189d309d582ab0eb7cdf984af7fb68a665aa092bef.

Because conf/eslint.js is missing from the npm archive, eslint cannot find the config file and an error occurs.

Can you re-upload the package or bump the version?

No, that is not correct.

Your problem is probably this:

If you want to use non-flat config, you need to pass the ESLINT_USE_FLAT_CONFIG environment variable

Thanks for the tip. Has that changed since 24.3.0? Everything was working fine for us at the previous version. Sindre Sorhus ***@***.***> schrieb am Di., 7. Mai 2024, 19:17:

I created a skeleton project that reproduces the issue: https://github.com/codders/grunt-eslint-176/

From what I can see, setting the ESLINT_USE_FLAT_CONFIG option has no effect. Can you confirm? (and apologies in advance is this is just a question with a really obvious answer)

I had the same issue and fixed it by migrating my old config to the new flat config format.

They now provide a command that can pretty much do it for you:

npx @eslint/migrate-config .eslintrc.json
