pyzeebe installation fails on Mac OS X Catalina (10.15.7) due to dependency on grpcio 1.32.0

[StevenDas-Tomo]

Describe the bug

pip install pyzeebe==2.2.2 on Mac OS X Catalina (10.15.7) fails due to an incompatibility between grpcio 1.32.0 and GCC:

grpc/grpc#25060 (comment)

Interestingly, pip installs the latest stable version of grpcio (1.34.0) without issue.

I'm using the following dependencies:

• pip: 20.2.3
• python: 3.9.1
• gcc:

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include/c++/4.2.1
Apple clang version 12.0.0 (clang-1200.0.32.28)
Target: x86_64-apple-darwin19.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

To Reproduce
Steps to reproduce the behavior:

1. Run pip install pyzeebe==2.2.2 on Mac OS X Catalina (10.15.7) with the exact dependencies specified above.

Expected behavior
Installation via pip should succeed without error.

Additional context
I notice that the grpcio dependency was removed 25 days ago:

https://github.com/JonatanMartens/pyzeebe/pull/91/files

Can we please release a new version of pyzeebe which includes this commit? That should unblock us.

Thank you so much for taking the time to maintain this useful library!

Unfortunately, I now see that zeebe-grpc also depends on version 1.32.0 of grpcio:

https://gitlab.com/stephane.ludwig/zeebe_python_grpc/-/blob/master/requirements_dev.txt

I'll raise the same issue over there.

Actually, it appears that the latest version of zeebe-grpc (0.25.1.0) depends on version 1.33.2 of grpc:

https://gitlab.com/stephane.ludwig/zeebe_python_grpc/-/blob/master/setup.py#L17

I had no trouble pip installing this version of zeebe-grpc onto my machine.

So it appears that pinning to version 0.25.1.0 of zeebe-grpc - and possibly earlier versions - should fix this issue.

Hey @StevenDas-Tomo, thanks for bringing this to our attention.
Version 2.2.3 was just released, so I'm closing this.
Please feel free to reopen this issue if you encounter any more problems.

I managed to reproduce this with pyzeebe==2.2.2 + Python 3.9 - not 3.8 or 3.7 however (interesting). It's resolved with pyzeebe==2.2.3. 🙂

I think this issue is related: https://gitlab.com/stephane.ludwig/zeebe_python_grpc/-/issues/4 - as it will allow the user to specify the grpc version (or simply resolve to latest, which wouldn't have caused this). I gave it a thumb-up, hopefully it will be prioritized soon.

Thank you so much for the fast turnaround, @JonatanMartens!

I can confirm that version 2.2.3 of pyzeebe unblocks me.
