Python pip installs fail - so many times - solution?

[Tracker]

Hi,

What's the solution to `pip install package` failing - usually there's some error like target of FreeBSD isn't supported or subprocess exited with some error ......... some of the packages install just fine but this is a major source of headache when you want to try out something in the Python world.

Is there some solution for this issue? Running pip packages is a pretty important requirement

PS: I also have linux_enable="YES" btw and the drivers loaded, and kldload shows linux drivers - in case that's of any consequence

Or is the only solution to run some VM with linux/ubuntu? That's the only one that comes to mind

Also possibly changing the text in these from "freebsd" as target to something like "linux" - should get it to work perhaps

or subprocess exited with some error

I can't help debug "some error". I can help debug concrete problems.

Seriously, there are some big issues with mixing pip and packages. But I have not experienced pip breaking with random errors that are hard to debug. The big issue is on operating systems where python installed are "locked down", meaning only the package manage system (pkg, apt, ...) is allowed to install python packages. That doesn't work in practice, because for many python things, OS packages are not available, so you have to bypass that protection. And afterwards you have to be very careful when upgrading things to not mix pip and pkg.

How about this - usually something similar many a times with something to do with "freebsd"

Start debugging the source files, file names are shown above. I suspect the problem is a mismatch between your OS and the package saying "freebsd14".
