Expected Behavior

kb runs.

Actual Behavior

Executing kb yields:

$ kb
Traceback (most recent call last):
  File "/home/yala/.local/bin/kb", line 5, in <module>
    from kb.main import main
  File "/home/yala/.local/lib/python3.10/site-packages/kb/main.py", line 19, in <module>
    from kb.commands.add import add
  File "/home/yala/.local/lib/python3.10/site-packages/kb/commands/add.py", line 19, in <module>
    import kb.db as db

    @attr.s(auto_attribs=True, frozen=True, slots=True)
AttributeError: module 'attr' has no attribute 's'

Steps to Reproduce the Problem

2. Execute kb
3. See the error above.

Please give a look at the FAQ section of the README

Ah yes ;) I saw this comment in another issue, why I returned here in the first place.

Unfortunately on my system running the commands as in

does not help:

AttributeError: module 'attr' has no attribute 's'

Please note that attrs (with s) has not been uninstalled, since it derives from the system installation and is outside of the /usr (as it says, despite being in /usr; well).

This might be an issue with my Python environment, after all. I should try reproducing this within a dedicated pyenv, Poetry, conda or asdf environment.

[gnebbia]

Wait there is no attrs installed? Yes please retry with a clean environment.

[almereyda]

Apparently, attrs is installed, but cannot be deleted (due to the lack of sudo):

Found existing installation: attrs 21.2.0
Not uninstalling attrs at /usr/lib/python3/dist-packages, outside environment /usr
Can't uninstall 'attrs'. No files were found to uninstall.

Working with a dedicated environment seems advisable here, as you suggest.

Still / again an issue:

]$ python3 --version
Python 3.12.3

Working with a dedicated environment for this one tool is not a viable solution—especially considering its purpose. I'm wondering if this is a python bug, as my system has attr and attrs both installed, one via local pip and the other via the system. (Path segments hidden with ....... )

Verified: There's something off about python3 the way it is "shipped" by Fedora
