Installation issues

[csbrasnett]

Describe the bug
Following the user install instructions on INSTALL.md does not result in successful installation. When the program is launched, an import error is thrown.

To Reproduce
Install SasView using one of the two command line user install instructions:

uv tool install sasview # tool installation
uv pip install sasview # inside a new virtual environment

Then launch with sasview.

Traceback gives:

  File "/pathstart/.venv/lib/python3.12/site-packages/sas/qtgui/MainWindow/PackageGatherer.py", line 5, in <module>
    import pkg_resources
ModuleNotFoundError: No module named 'pkg_resources'

This I do not understand because this dependency was removed in fa2d844, but appears to still persist from the pypi deployment.

Expected behavior
Program launches without error

SasView version (please complete the following information):

• Version: 6.1.3

Operating system (please complete the following information):

• OS: MacOS 26.2, RHEL 8.10

Installation method (please complete the following information):

• Installed: as described above

Additional context
Python 3.12 used across both OS

Thanks for the report, @csbrasnett. I see you are running py3.12, which should be fine, though our v6.1.x binaries were built using python 3.11.

This I do not understand because this dependency was removed in fa2d844, but appears to still persist from the pypi deployment.

The dependency was removed from our main branch, but our v6.1.x releases still depend upon it. See v6.1.3 branch for reference. I would suggest you try to downgrade your setuptools to v81.0.0, which should resolve the issue.

I will update our installation instructions for the pypi distributions and add a note to the release regarding the requirement.
