The above error line points to a missing .eslintrc config file missing in your repository. You may not have committed it into your repository code and pushed it to GitHub.

If you clone your repository into a clean directory onto your machine and run the build command exactly like Netlify would, you should see the same error.

Note: Make sure your repository does have a .gitignore file which should also be included with the following. This doesn't affect anything, but might help you avoid pushing development and production files into your repository.

node_modules/
dist/
