setuptools-70.0.0 doesn't seem to work with ParallelCluster

[rmarable-flaretx]

AWS ParallelCluster 3.9.0 and beyond don't seem to work with the most recently released version of setuptools (70.0.0) on OSX.

 ❯ pcluster version
Traceback (most recent call last):

Revering back to setuptools-69.5.1 seems to fix the issue.

❯ pcluster version
{
  "version": "3.9.0"
}

I didn't test this, but I suspect the same is true for Linux as well.

Hi @rmarable-flaretx ,

It's recommended to install pcluster in a Python virtual env, to avoid conflicts with other Python dependencies.
See instructions here: https://docs.aws.amazon.com/parallelcluster/latest/ug/install-v3-virtual-environment.html

This will solve any kind of library incompatibility issues.

I am using a virtual Python environment. The issue is that the most recent version of setuptools doesn't seem to work; downgrading to 69.5.1 did.

@rmarable-flaretx thanks for the workaround, reverting to setuptools==69.5.1 did the trick for me. Looks like setuptools==70.0.0 deprecated pkg_resources which is causing the error. https://setuptools.pypa.io/en/latest/pkg_resources.html

I just found that we were aware of this issue, so we pinned setuptools a month ago: #6251 the fix has been included starting from ParallelCluster 3.9.1

Thank you @enrico-usai!
