Greenlet is still unavailable for arm64?

[mt1ger]

I am not sure if I did anything wrong? I still can not install arm64 version neovim since pynvim is not available. I guess greenlet is still not ready.

Please help me out. Thanks. P.S.: I have uninstalled greenlet from pip and installed greenlet from the source. #473

pip uninstall greenlet
pip install -I greenlet --no-binary greenlet

Please read the error messages. Your installed binary is x86.

[mt1ger]

@Shougo I know I installed x86 version. That is basically where the error happened. However, can you tell me how to install the specific arm64 version of greenlet? pip install is not an option. It says it installed an arm64 version however it does not. I tried install from source and got the same error.

Still the same error...

It is not pynvim issue. https://github.com/python-greenlet/greenlet/issues/234

[mt1ger]

Ok. I got it. Thank you for your replies.

[yoshiya0503]

It is easy to build and install from source code.

1 clone greenlet to your appropriate directory. (https://github.com/python-greenlet/greenlet)

2 check setup.py and setup.cfg

3 python setup.py bdist_wheel (build on your arm64 environment)

4 pip install dist/xxxx.whl (install from created wheel file for arm64)

5 pip list (you can check greenlet your original version)

6 check nvim (:checkhealth and see your python)

@yoshiya0503 i tried your steps but got the same issue

ImportError: dlopen(/opt/homebrew/lib/python3.9/site-packages/greenlet/_greenlet.cpython-39-darwin.so, 0x0002): tried: '/opt/homebrew/lib/python3.9/site-packages/greenlet/_greenlet.cpython-39-darwin.so' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e'))

[vvuk]

FWIW -- building and installing from source code works, but you have to edit setup.py and add the following to the if sys.platform == 'darwin' section:

      cpp_compile_args.append("-arch")
      cpp_compile_args.append("arm64")
      cpp_link_args.append("-arch")
      cpp_link_args.append("arm64")

for whatever reason building bdist_ext forces -arch x86_64.

I added those but it is not working :(
