Describe the Bug

when I run next build, it asked to install eslint-config-next. So I did to try the new feature.

after that I got numerous errors, seems like one for every page that look like this:

./src/pages/mypage.tsx
Error: Parsing error: Cannot read file '/full/path/to/git/clone/client/client/tsconfig.json'.

Yes, notice the client/client, that looks like the bug.

my git project structure is this:

root
  package.json
  client <--- where next build is run!!!
    package.json 
    tsconfig.json
    src
      pages   
        mypage.tsx

Expected Behavior

These errors should not happen. I also have my own eslint set up in the root of the repo, but I want to see what this feature offers before disabling it.

To Reproduce

Try to setup a project like what I've described, and run next build from the client directory.

Tried to quickly reproduce and couldn't unfortunately 😞.

Is next installed in client/package.json or in the root folder? Are you also seeing the same errors when running next lint?

[jimisaacs]

installed in client/package.json and client is a yarn workspace. Yes, same result with next lint.

[jimisaacs]

cd client
yarn next lint

Thanks for the clarification @jimisaacs. Unfortunately I can't seem to reproduce this issue, but could you try adding the following to your .eslintrc:

parserOptions: {
  project: "tsconfig.json",
  tsconfigRootDir: __dirname,
  sourceType: "module",
}

It sounds like ESLint is running for you on a separate directory than where tsconfig.json is located, so hopefully this fixes things.

@housseindjirdeh I have the same issue in a fully reproduced use case (glad to CI) : thisismydesign/next-nest#23

• Lint is passing but not build
• I tried several ways but nothing works

[thisismydesign]

I fixed this with the eslint dirs option:

src/client/next.config.js

module.exports = {
  eslint: {
    dirs: ['src/client'],
  },
};

After this, next build works.

I'm using it here: https://github.com/thisismydesign/nestjs-starter > thisismydesign/next-nest#83
