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")

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
