Current Behavior

When I ran tests with webpack build, the following error occurred.

Hey @CoderK! We really appreciate you taking the time to report an issue. The collaborators
on this project attempt to help as many people as possible, but we're a limited number of volunteers,
so it's possible this won't be addressed swiftly.

If you need any help, or just have general Babel or JavaScript questions, we have a vibrant Slack
community that typically always has someone willing to help. You can sign-up here
for an invite.

This method was added in #7712 so pretty sure it's just using a version that is old somehow

I would just ask that you clear your cache/node_modules, and make sure your dependencies are the same version. Having some be ^ like "@babel/plugin-proposal-decorators": "^7.0.0-beta.47", is confusing and is probably the issue.

1. Update babel/core to beta.49. All the Babel packages should be at the same version
2. Don't use ^ in beta versions, since there could be breaking changes
