Fails to install azure-cli (which is installed just fine with pip)

[facundobatista]

Working with uv 0.5.5 under Ubuntu 24.04.1 LTS.

I tried the following uv --verbose tool run --from azure-cli az --version, which end up failing with

Traceback (most recent call last):
  File "<frozen runpy>", line 189, in _run_module_as_main
  File "<frozen runpy>", line 112, in _get_module_details
  File "/home/facundo/.cache/uv/archive-v0/It-BMRRUxK61HFCnOgJeg/lib/python3.12/site-packages/azure/__init__.py", line 1, in <module>
    __import__('pkg_resources').declare_namespace(__name__)
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named 'pkg_resources'

(full verbose run in this gist way too long to include it here)

Note that azure-cli is installable just fine with pip (see this other gist for the logs).

Strangely, in the pip installation there is no lib/python3.12/site-packages/azure/__init__.py file... but hey, it works:

I think you might need --with setuptools? Though I'm not sure why. Does that fix it for you? azure-cli might be assuming something non-standard about the virtual environment.

[dimbleby]

there are lots of duplicates, uv failure to install azure-cli is always about pre-releases

[facundobatista]

@charliermarsh But setuptools is a dependency of azure-cli (declared in its setup.py), so why would one need to indicate that separately?

[facundobatista]

@dimbleby duplicated issues, you mean? not following, about pre-releases of what?

[facundobatista]

I've been able to go deep on this. It results it's not a "bug" in uv, but more than "a behaviour difference" with pip.

While pip prefers stable versions (and not pre-releases) but still selects a pre-release if no other option available (*1), uv just refuses to use it unless a flag is specified (*2).

So, I'll go forward and close this (just re-open if you think this is something that actually should be fixed).

(*1) From the pip gitst linked above:

Collecting azure-cli
  Using cached azure_cli-2.67.0-py3-none-any.whl.metadata (8.4 kB)
...
Collecting azure-keyvault-administration==4.4.0b2 (from azure-cli)
  Using cached azure_keyvault_administration-4.4.0b2-py3-none-any.whl.metadata (30 kB)
...
Successfully installed ... azure-keyvault-administration-4.4.0b2 ...

(testaz) 14:37:24|facundo@trifon:~/temp$ az --version
azure-cli                         2.67.0

(*2) It happened uv was installing a broken old version (2.0.67 which is easily visually confused with 2.67.0)... if forced to last version, the detail of why it was not chosing the last version was more evident:

31:44|facundo@trifon:~$ uv --verbose tool run --from "azure-cli==2.67" az --version
DEBUG uv 0.5.5
...
  × No solution found when resolving tool dependencies:
  ╰─▶ Because there is no version of azure-keyvault-administration==4.4.0b2 and azure-cli==2.67.0 depends on azure-keyvault-administration==4.4.0b2, we can conclude that azure-cli==2.67.0 cannot be used.
      And because you require azure-cli==2.67, we can conclude that your requirements are unsatisfiable.
