babel: Create react app is broken because of 7.9.0

https://github.com/facebook/create-react-app/issues/8680

Describe the bug

Running npm run build will fail on any project, even on a vanilla app created with create-react-app will fail with the following error:

Error: [BABEL] /Users/<username>/Projects/my-app/src/index.js: Could not find plugin "proposal-numeric-separator". Ensure there is an entry in ./available-plugins.js for it. (While processing: "/Users/<username>/Projects/my-app/node_modules/babel-preset-react-app/index.js$0")

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Try adding "@babel/compat-data": "~7.8.0" to your "devDependencies", deleting "@babel/compat-data" from package-lock.json and running npm install.

If you are using yarn, this is better: https://github.com/facebook/create-react-app/issues/8680#issuecomment-601851525

Lockfiles were introduced to help mitigate the problem of shifting dependencies. Highly recommend using one!

My pipelines broke, I have the same error. Does someone have a solution for this bug?

@jblevins1991 We fixed it in 7.8.7.

If you depend on open source software you are not helping to maintain and you are not supporting in any way (neither with human time nor financially), you are not entitled to complain about what the maintainers are doing. I assure you that we are trying to do our best. Why is this such a hard concept in the tech industry.

Modern development environment with babel, react and other dependencies will create havoc all the times. Changes break suddenly and errors are not clear.

Our pipeline is broken because of this. Can anyone recommend a react-scripts version to roll back to that works?

Thank you!!

@wandersoncesar It’s unexpected that it broke angular 🤔 Avoid @babel/preset-env v7.8.0-7.8.6 which are broken should be enough for you.

Hey @Lukavyi! 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."
