Unable to pip install 1.10.2.1 on Mac

[foundry-markf]

Hi,

I'm unable to pip install 1.10.2.1 onto my Mac (and several others).

The error I've seen is:

WARNING: You are using pip version 19.2.3, however version 21.2.4 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

I also have CMake in my virtual environment:

(env382) FWMBP064:src mark.final$ cmake --version
cmake version 3.21.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).
(env382) FWMBP064:src mark.final$ which cmake
/Users/mark.final/dev/conan/env382/bin/cmake

and this is

(env382) FWMBP064:src mark.final$ python --version
Python 3.8.2

and my system info

(env382) FWMBP064:src mark.final$ uname -a
Darwin FWMBP064.local 18.7.0 Darwin Kernel Version 18.7.0: Tue Jun 22 19:37:08 PDT 2021; root:xnu-4903.278.70~1/RELEASE_X86_64 x86_64

I can pip install ninja==1.10.2 without error.

Just as I posted, I thought I should upgrade pip to see if that makes a difference.

(env382) FWMBP064:src mark.final$ pip install -U pip

and it does.

Sorry for the noise!

Thanks for the report @foundry-markf.
That's not noise, it even has all information to see that 1.10.2.1 is missing the macosx_10_9_x86_64 platform tag on the macOS wheel. We'll need to fix this.
