Cannot install CadQuery via pip on Scientific Linux OS #1194

Open helen-brooks opened 2 years ago

Description of Issue

I have been unable to install cadquery 2.x via pip on a system where the OS is Scientific Linux. This is within the context of a fairly complex project which historically has had some trouble with conda, and therefore I have a desire to avoid conda unless necessary. I do not have root permissions on the system in question. I'm operating in a virtual python environment, with python version 3.8.2 and pip version 22.3.1

So far I have tried installing via

In all cases I get errors looking like

ERROR: Could not find a version that satisfies the requirement cadquery-ocp<7.7,>=7.6 (from cadquery[dev]) (from versions: none)
ERROR: No matching distribution found for cadquery-ocp<7.7,>=7.6

In attempt to install cadquery-ocp 7.6 directly I have tried:

all to no avail.

I'm not sure, this issue seemed similar but different: https://github.com/CadQuery/cadquery/issues/1182

Desired outcome

I'm raising this issue to find out if there's a fix to any of the above that will result in a route to install this package via pip on Scienfic Linux. Any help would be appreciated!

You can check a platform's supported wheels using pip debug --verbose. I think SL7 supports manylinux_2_17 policy but not cadquery-ocp's requirement of manylinux_2_31. You can also use this table to see which distros support which policies.

This is a known limitation and I think using conda would be the easiest way forward.
