Missing `estraverse` dependency

[cdfa]

Hi, I tried this project today and at first glance it seems to work very well. However, when I tried installing the dependencies of the example project with pnpm, I got this error on compilation:

/src/index.js
Line 0:  Parsing error: Cannot find module 'estraverse'

However, there is no such line in examples/src/index.js.
This probably means one of the (deep) dependencies is missing estraverse as a dependency in their package.json, but they're relying on it being installed in the node_modules folder because it's a dependency of one of their dependencies. According to npm's specification, only direct dependencies have to be installed in the node_modules folder, which is exactly what pnpm does.

Sadly, the error message doesn't give me any idea of what package might be missing the estraverse dependency, which is where I hope someone can help out.

For anyone who runs into this and doesn't know, the issue can be resolved by using pnpm's --shamefully-flatten flag.

I recommend reporting that upstream.

I want to, but to which package?
