maturin 0.12.0 — broken on macOS

[jnicholls]

Please provide the following information:

• Your python version (python -V): Python 3.9.8
• Your pip version (pip -V): 21.3.1
  • If this isn't the latest pip version, have you checked using the latest pip version?
• The version of the bindings you're using, if any (e.g. pyo3, rust-cpython or cffi): pyo3 0.14.x
• Does cargo build work? Yes
• If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

Please list the exact steps required to reproduce your error with all command output and if possible with a repository:
Just a simple build:

❯ maturin develop
🍹 Building a mixed python/rust project
🔗 Found pyo3 bindings with abi3 support for Python ≥ 3.8
🐍 Not using a specific python interpreter (With abi3, an interpreter is only required on windows)
💥 maturin failed
  Caused by: Invalid platform string from `sysconfig.get_platform()`

0.12.0 introduced this get_platform inspection code, which is not parsing correctly it would seem. 0.11.x works fine.

My sysconfig.get_platform() value is macosx-11-arm64 on my M1 and macosx-11-x86_64 on my Intel. Neither are working with 0.12.0.

Thanks in advance!

I've determined it is the base_version.split_once('.') call. That returns None because there is no dot-separated version in my platform string, it is simply 11. This is the case on both Big Sur 11.5.2, as well as Monterey 12.0.1, interestingly enough.

Hope this helps. Thanks!

Thanks for the report, please give 0.12.1-beta.1 a try when it‘s released to PyPI. You can install it by using pip install -U --pre maturin.
