When I run yarn run lint fileName, it returns

error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

What I've tried are yarn install and yarn upgrade. npm install is also done. Oddly, ESLint itself is working so it can edit my file in spite of this error. However, I would like to solve this error.

This is my package.json. I am not sure what is the problem. I would appreciate any suggestions.

It could be that there is a lint finding that throws an error. ESLint does this if the rule is set to error and not warning. See discussion at https://github.com/eslint/eslint/issues/7933 for the issue in npm (yarn may have same problem)

The short version is that you have to either:

  • fix all lint findings
  • change the rules to throw warning instead of error
  • force your command to exit with 0 (e.g. package.json has "lint": "eslint app/;exit 0")

While it's not recommended you can silence the exit code in both by adding the --silent flag.

For npm:

npm run lint /file/path --silent

For yarn:

yarn run --silent lint /file/path
