Current and expected behavior

The result I prefer is

babelRunner1
ignore:
console.log('ignore');
main:
console.log('main');

babelRunner2
ignore:
console.log('ignore');
main:
console.log('main');

but the truth is

babelRunner1
ignore:
ignore.js config is null
main:
console.log('main');

babelRunner2
ignore:
console.log('ignore');
main:
console.log('main');

Environment

 System:
    OS: macOS 12.4
  Binaries:
    Node: 16.16.0 - ~/.nvm/versions/node/v16.16.0/bin/node
    Yarn: 1.22.10 - /usr/local/bin/yarn
    npm: 8.19.2 - ~/.nvm/versions/node/v16.16.0/bin/npm
    pnpm: 8.5.1 - ~/Library/pnpm/pnpm
  npmPackages:
    @babel/core: ^7.23.5 => 7.23.5 

Possible solution

If it is a bug, the reason maybe locale in here. ignoreFile will not be processed when babelrc is not equal to false.

If it is a feature, just close the issue.

It is a feature. The .babelignore and .babelrc are both Babel 6 era legacy config files. When babelrc is false, the .babelignore will not be loaded, either. You can specify the ignore option in babel.config.*. We can clarify that in the docs.

Got it. Thank you!
