研究方向
Start by reproducing the reported conda-forge installation with basemap and NumPy 2.5, then compare the dependency constraints that cause NumPy, pyshp, and packaging to be downgraded. Done means basemap can be installed in a recent environment without downgrading NumPy; the issue mentions no repository files or tests to start from.

描述
I guess this is some kind of follow-up of #647 , as requested by @thebaptiste
Note: I'm using conda and everything (including conda) from conda-forge
I have tried several times this week to add basemap to a fairly complex (but up-to-date) Python environment, and had to kill conda because nothing happened. That is conda install was not moving anymore, but the conda process was using more and more resources. This time, I killed a 100% CPU conda process using 13 Gb after 200 minutes
So I tried to install only basemap, with conda create -n basemap_test basemap in order to check I could install it at all! This worked perfectly and quickly, but I ended up with numpy 2.3.5 (not numpy 2.4)
If conda was not working with my complex environment, I thought I would use mamba again, which I have not done since mamba became the default solver of conda. And I quickly got a result (no mamba deadlock or guru meditation)!! Trouble is that mamba wants to downgrade the installed numpy, which is a no-go. And also wants to downgrade pyshp (and packaging) but I don't know anything about these

Any thoughts on that, by somebody who knows about packages dependencies and constraints?
Note that the environment where I installed only basemap has pyshp 2.3.1. Could the problem come from pyshp?
Full list of the basemap-only environment below
I have asked the student who wanted basemap to use cartopy instead, so this is not a blocking problem. But it would be nice to still be able to install basemap in a recent environment, if it does not require too much work from the people in charge :-)
