Bug with Miniforge3-MacOSX-x86_64, MacOS11, Wrong Compatible tags

[gutsyy]

Issue:
Wront Compatible Tags
Test:
Python 3.8 from the system:

/usr/bin/python3 -c "import platform; print(platform.platform())"
macOS-11.0.1-x86_64-i386-64bit

Python 3.9 installed with homebrew:

/usr/local/bin/python3 -c "import platform; print(platform.platform())"
macOS-11.0.1-x86_64-i386-64bit

Python 3.8 from a conda-forge env:

/Users/ogrisel/miniforge3/envs/py38/bin/python -c "import platform; print(platform.platform())"
macOS-10.16-x86_64-i386-64bit

So conda-forge's Python is indeed pretending to be installed on a fake 10.16 version of macOS to bypass this problem with pip 20.2.4

How to fix that? Thanks a lot.

For situational awareness, I think this is not necessarily a bug with Miniforge but it could be Conda's Python as a whole. I get this same 'issue' on Anaconda where a Python interpreter for Intel macOS 11.2 is considered 10_16 where as on an Apple Silicon macOS 11.2, it's 11_0.

Can you confirm that python 3.9 works fine?

[mwidjaja1]

@isuruf For me (admittedly I'm using Anaconda), Python 3.9 does not work fine

python --version
Python 3.9.1

which python
/Users/matthew/opt/anaconda3/envs/test/bin/python

python  -c "import platform; print(platform.platform())"
macOS-10.16-x86_64-i386-64bit

[isuruf]

can you try conda-forge?

[mwidjaja1]

@isuruf Sure, same effect

~/miniforge3/bin/python -c "import platform; print(platform.platform())"
macOS-10.16-x86_64-i386-64bit

[isuruf]

Can you show conda info?

[isuruf]

and conda list?

[isuruf]

Can you try creating a python=3.9 env, confirm the bug exists there and show conda list?

[isuruf]

Also what do you get with platform.uname()?

[gutsyy]

env python=3.9

I think python=3.9 env Compatible tags is right. The problem is python=3.8 env. Some .whl release only have python38 compatible tags, maybe download the .whl and rename _cp38_cp38_macosx_11_0 to _cp38_cp38_macosx_10_16 can fix that.

[isuruf]

Thanks for the info. This is a upstream issue if python is built with SDK < 11.0 and used with Big Sur. See release note at https://www.python.org/downloads/release/python-387/ about 3.8.7 not fully supporting Big Sur.

You'll have to backport the PR python/cpython#23295 to 3.8 branch in cpython.

[isuruf]

To workaround this, do export SYSTEM_VERSION_COMPAT=0 before running python

Thank u lot. It works fine!
