There was a problem hiding this comment.
There are 4 packages whose types circularly depend on @babel/traverse. Lets just ignore those errors for now (@babel/traverse will be in the dependencies anyway), but I will think of a better solution before going stable.

Fixes #1, Fixes #2This PR makes sure that all our
import types only reference packages that are listed independencies/peerDependencies. This is done mainly in two ways:@babel/core, so they can importNodePath/Visitor/Scope/typesfrom there rather than from@babel/traverse/@babel/types@babel/traverse/@babel/types: if a helper expects aNodePathas a parameter, you already have to have@babel/traverse/@babel/typesin your dependencies so this is not causing extra deps.To (2) there are some exceptions:
babel-helper-builder-react-jsxandbabel-helper-plugin-utilsonly make sense when using with a full plugin (and not directly with parser+traverse), so I added@babel/coreas a peer dependency (but only for Babel 8)babel-helper-fixturesis also only needed when testing plugins, so I added@babel/coreas a peer depThis PR doesn't lint
@babel/standaloneand@babel/parsersince those are bundled, but we should probably add@babel/typesas a dependency of@babel/parser. I don't really like doing it since it's perfectly reasonable to use@babel/parserwithout also using@babel/types, but on the other hand if the dependency is only used inimport typeit won't actually affect anything at runtime (it won't be loaded) so adding it is not too bad.There is one remaining lint error fixed by #16493.
