Steps to reproduce

I've got a spec file setup in my Components directory, every time I try to run the Jest commands in my Vue project created with the CLI it complains about my Babel configuration despite being the defaults:

My babel config:

module.exports = {
  presets: [
    '@vue/cli-plugin-babel/preset'
  ]
}

Apparently this is invalid? And commands fail with ReferenceError: [BABEL] unknown: Unknown option

What is expected?

Commands should not fail with default config

What is actually happening?

Commands are failing

---

I've tried changing the config and removing it, neither of these work.

Hi, thanks for your report.
Would you please reduce your issue to a small reproducible example (e.g. a GitHub repository together with instructions on how to get to the problem)? Without a runnable example, it would be difficult for us to find out what is going wrong.

I fixed it by installing babel-core@ ^7.0.0-bridge.0
