Can not compile on macOS 12.4 + Xcode 13.5 (Python 3.8.9)

[dreampiggy]

This package lock dulwich to a really old version, which can not compile on latest Python version.

ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.

We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.

gittle 0.5.0 requires dulwich==0.9.7, but you'll have dulwich 0.20.43 which is incompatible.

However, if I install dulwich 0.20.43, it can successfully built.

Successfully built pycrypto psutil dulwich
