Conditional Requirements In Setup.py

I'm writing a library that's dependent on file-magic, which works just fine for most platforms, but in Alpine Linux, file-magic won't work so I need to instead use the python-magic

Solution 1:

You probably want to use the platform module to try to identify the system details.

Best bet is to try and use a combo of platform.architecture(), platform.platform(), and platform.system() with proper error handling and consideration of all possible return info.

Example:

I am running on Win10, here are the outputs of those functions (and one more):

>>> import platform
>>> print(platform.architecture())
('32bit', 'WindowsPE')
>>> print(platform.platform())
Windows-10-10.0.17134-SP0
>>> print(platform.processor())
Intel64 Family 6 Model 142 Stepping 10, GenuineIntel
>>> print(platform.system())
Windows

Edit

The above answer does not necessarily return the info that you want (I left out mention of any deprecated functions from the platform module).

Digging a little deeper, yields this SO result which explains that the built-in platform functions for gathering distro names are deprecated.

The official docs point in the direction of a PyPi package called distro. The distro docs on PyPi acknowledge the need for this type of info and an example usage found there looks like this:

>>> import distro
>>> distro.linux_distribution(full_distribution_name=False)
('centos', '7.1.1503', 'Core')
