Bug: ESLint API cannot find eslint-recommended.js

Environment

Node version: v16.10.0 npm version: 7.24.0 Local ESLint version: 8.8.0 Global ESLint version: N/A Operating System: macOS Big Sur

What parser are you using?

Default (Espree)

What did you do?

To reproduce the issue:

• git clone https://github.com/daidodo/eslint-api-issue.git
• cd eslint-api-issue && npm i && npx webpack
• node dist/main.js src/index.ts

What did you expect to happen?

I expect the output is the ESLint resolved config for the given file. If you run npx tsc && node dist/main.js src/index.ts, you can get:

ESLint version: 8.8.0
eslint object: ESLint {}

What actually happened?

If webpacked, the output would be:

ESLint version: 8.8.0
eslint object: ESLint {}

Additional comments

I’ve submitted a similar issue (https://github.com/eslint/eslint/issues/13974) but got aged. My guess is the __dirname in lib/cli-engine/cli-engine.js causes the issue. But I don’t have enough context to confirm or fix it.

Thanks!

Reopening as this isn’t fixed until https://github.com/eslint/eslint/pull/15616 gets merged.

I don’t know. Why don’t you try it and see what happens?
