Steps to reproduce

1. create a babel.config.js file that excludes a file:

// Export the babel config
  module.exports = {
    presets: ['@vue/cli-plugin-babel/preset'],

    // Exclude from transpilation
    exclude: [
      /(ignoreme\.). /, // Exclude filenames containing `ignoreme`
    ],
  };

2. start the devServer: npm run serve
3. following error triggers: Error: Configuration contains string/RegExp pattern, but no filename was passed to Babel

No error occurs when reverting @vue/cli-plugin-babel to 4.0.5.

What is expected?

No error occurs when starting the devServer.

What is actually happening?

Following error is shown: Error: Configuration contains string/RegExp pattern, but no filename was passed to Babel

Got it. It's due to this line:

vue-cli/packages/@vue/cli-plugin-babel/index.js

Line 27 in 7a835df

babel.loadPartialConfig()

quick question: this issue is closed but not fixed in the current version. Is there any indication in which version this will land and/or what the schedule is for releasing this new version?

[haoqunjiang]

Sorry for the delay. I'll release a new version this weekend.

I didn't do the release earlier because I was going to take vacation earlier this month and then the holiday season arrived, so I'm afraid that people wouldn't have the capacity to deal with possible regressions in the new release.

Now that I'm back to work I'll do the release soon.
