Error: Cannot find module '@babel/runtime-corejs2/helpers/interopRequireWildcard'

I tried upgrading my library (which is using babel-runtime) to Babel 7 today and I get this error when running it.

Error: Cannot find module '@babel/runtime-corejs2/helpers/interopRequireDefault'

The config is the same as in the Upgrade manual:

{
	"presets": ["@babel/preset-env"],

	"plugins":
	[
		["@babel/plugin-transform-runtime", { corejs: 2 }],
		...
	]
}

Hey @catamphetamine! We really appreciate you taking the time to report an issue. The collaborators

Ok, it needed:

 npm install @babel/runtime-corejs2 --save

Yup! Glad you got it working. Can we improve the documentation around this?

@loganfsmyth Not much I guess, it's just a bit overwhelming for anyone to migrate infrastructure to a new major version, so many things get overlooked due to how human perception/consciousness work.
I mean it is written there to install the package, but I decided to just overlook it.
