Unable to install in pypy

[pacrob]

Attempting to install coincurve in both pypy3.10 and pypy3.11 on Ubuntu results in:

        File "/tmp/pip-install-qfbnaz4o/coincurve_afdb4624c0fc432786b913d146e8d692/hatch_build.py", line 26, in initialize
          cffi_shared_lib = _cffi_backend.__file__
      AttributeError: module '_cffi_backend' has no attribute '__file__'

I've gone through the install docs, but no dice. Any recommendations?

I also just ran into this issue. Have you had any luck resolving it?

Nothing yet.

It would help if one of you could run PyPy with CFFI installed and then print(dir(_cffi_backend))

Per PyPy, they are recommending that since it's already installed in PyPy, that it shouldn't be attempted to install again.

That seems like a good approach, thanks.
