Currently getting this while intending to use babel plugin for format.js:
Error: Requires Babel "^7.0.0-0", but was loaded with "6.26.3". If you are sure you have a compatible version of @babel/core, it is likely that something in your build process is loading the wrong version. Inspect the stack trace of this error to look for the first entry that doesn't mention "@babel/core" or "babel-core" to see what is calling Babel.

Move to use babel 7 APIs happened on June 17
Attemps to use version older of babel-plugin-react-intl either still require 7:
https://www.npmjs.com/package/babel-plugin-react-intl/v/4.0.0
4.0 was published a year ago according to npm. Even older versions, e.g.:
https://www.npmjs.com/package/babel-plugin-react-intl/v/3.0.0
just don't work at all. Giving this error on page load:
utils.js?73c2:76 Uncaught Error: [@formatjs/intl] An `id` must be provided to format a message.
at invariant (utils.js?73c2:76)
at formatMessage (message.js?ab38:41)
at formatMessage (provider.js?90d5:76)
at eval (message.js?7c48:60)
Docs on npm for 3.0 are quite a bit different. It seems that the repo was moved. Here was the original location (with some docs for that version):

Attempting to upgrade babel so far was not much more successful. It involved upgrading a ton of libraries that depend on babel-core. Not only that but this is where babel makes it's jump to the @babel/ format so the packages must all be replaced by their new scoped equivalent. I have my current attempt in a branch but it is currently stuck on this error:
/Users/alex/projects/you/YOU-Frontend/node_modules/@babel/core/lib/config/files/plugins.js:152

Error: The 'decorators' plugin requires a 'decoratorsBeforeExport' option, whose value must be a boolean. If you are migrating from Babylon/Babel 6 or want to use the old decorators proposal, you should use the 'decorators-legacy' plugin instead of 'decorators'.
