Add system install test for Amazon Linux

[zanieb]

Supersedes #1534

[zanieb]

@charliermarsh this looks legitimately wrong? https://github.com/astral-sh/uv/actions/runs/8259113036/job/22592520139

Same failure over in #2402

[charliermarsh]

Not necessarily. It depends on what sys.path is. Where does pip install into? It's possible that that's the right place, and the directory just doesn't exist yet. (I genuinely don't know, I'm just saying it's possible we're wrong to assume the directory has to exist in advance.)

[zanieb]

In CentOS (I just have the image around locally):

[root@bf9d80fad201 /]# python3 -c "import sys; print(sys.path)"

Suggests you're right — #2404

[charliermarsh]

Yeah it does look like pip is installing into the same place. Although why isn't /usr/local/lib/python3.9/site-packages on sys.path?

[zanieb]

Oh yeah I read /usr/lib/python3.9/site-packages as /usr/local/lib/... umm I'm not sure :)

[charliermarsh]

Can you check that import pylint or whatever works in that Python?

[charliermarsh]

Or you can share the Dockerfile and I can debug it.

[zanieb]

[root@d4f5af1c6ac6 /]# python3 -c "import pylint" works

I'm just copy-pasting the setup commands for CentOS from the CI workflow

[zanieb]

Interestingly now the sys.path includes it

[root@d4f5af1c6ac6 /]# python3 -c "import sys; print(sys.path)" 
['', '/usr/lib64/python39.zip', '/usr/lib64/python3.9', '/usr/lib64/python3.9/lib-dynload', '/usr/local/lib/python3.9/site-packages', '/usr/lib64/python3.9/site-packages', '/usr/lib/python3.9/site-packages']

[zanieb]

It gets added when you pip install something :)

[zanieb]

Or, more concretely, when it exists

[root@f381759817d2 /]# python3 -c "import sys; print(sys.path)"
['', '/usr/lib64/python39.zip', '/usr/lib64/python3.9', '/usr/lib64/python3.9/lib-dynload', '/usr/lib64/python3.9/site-packages', '/usr/lib/python3.9/site-packages']
[root@f381759817d2 /]# mkdir -p '/usr/local/lib/python3.9/site-packages'
[root@f381759817d2 /]# python3 -c "import sys; print(sys.path)"
['', '/usr/lib64/python39.zip', '/usr/lib64/python3.9', '/usr/lib64/python3.9/lib-dynload', '/usr/local/lib/python3.9/site-packages', '/usr/lib64/python3.9/site-packages', '/usr/lib/python3.9/site-packages']

[zanieb]

Done in #2413 instead

[charliermarsh]

Thank you!
