@Brian Huimin Kang (US) Python worker does not support running on Mac M1 at the moment. There is multiple issue that are tracked in below links and the official document also cover it with the workaround: https://learn.microsoft.com/en-us/azure/azure-functions/functions-run-local?tabs=v4%2Cwindows%2Ccsharp%2Cportal%2Cbash#x86-emulation-on-arm64

Answer 2

Thanks for all your answer. Sorry for late reply

I find a way to work out this issue. It might only work for my case. But for others, it might give you some insight.

Steps:

1. install miniforge3 and then create a x86_64 environment
2. install azure-functions-core-tools with npm
3. create the .venv environment by leveraging the x86_64 env
4. update /usr/local/lib/node_modules/azure-functions-core-tools/bin/workers/python/worker.config.json :

     "defaultWorkerPath":"%FUNCTIONS_WORKER_RUNTIME_VERSION%/{os}/X64/worker.py",
   

   5. when launch your python azure function, please activate .venv env first .
