Functions:

  HttpTrigger: [GET,POST] http://localhost:7071/api/HttpTrigger

How to reproduce

>virtualenv .venv
>source .venv/bin/activate
>func init
>>3 (python)
>func new
>>5 (HttpTrigger)
>func host start

System

>func -V

>python -V

Additional info
Curiously when trying to run the function from within vscode I get a different, but similar error
ModuleNotFoundError: No module named '_ctypes'
Maybe that's a hint as to whats going on.

@Hazhzeng @vrdmr can you help? Thanks.

@Valansch thank you for reporting this issue. We are working to reproduce this issue. In the meantime, we have not yet validated support on m1, so we will need to go through that process before we can assure compatibility.

Thank you for your reply. I know the M1 is not officially supported. But If you find a workaround in the meantime I would be grateful if you could share it here.

One piece of information that I left out of the original issue:
When initially setting up the azure functions core tool I could actually run and debug the function.
I do not know what changed to cause it to break and after investigating the issue I do not understand why it worked in the first place...

I'm having similar problems - open #2397 for my issue. In may case adding the Azure IoT Python SDK caused the issue.

Hi @Valansch,

Looks like gRPC doesn't have an M1 wheel yet (required for python runtime to communicate with the host) - https://pypi.org/project/grpcio/#files. This is why this won't work correctly. I don't know if pip install grpcio builds it correctly from the source. We are trying that from our end.

This is a surprise for me.

When initially setting up the azure functions core tool I could actually run and debug the function.
I do not know what changed to cause it to break and after investigating the issue I do not understand why it worked in the first place...

Could you try the following in the terminal (not in VSCode, and not debugging) -

.venv/bin/activate
func host start

And paste the output?

Edit -
Re read your message. The first stack trace for that info. So got my answer. Can you please re-install CoreTools and the output of func host start again?

You are right pip install grpci does not build:

[2021-01-23T08:08:01.197Z] Exceeded language worker restart retry count for runtime:python. Shutting down and proactively recycling the Functions Host to recover

However I found a workaround here:
apple/tensorflow_macos#48

Using the python 3.8.2 shipped from xcode allows me to run CoreTools again.
I have been using python from pyenv before, that probably broke it.

This workaround works for me. If you need any info from me in order to fix this issue I will gladly help.

Consolidating M1 issues. Will use Azure/azure-functions-python-worker#915 for Python work and #2834 for core tools
