+1 to exactly this. I was going to post exactly the same comment about uv. That project has put a lot of work into specifically creating easily redistributable Python installs... so other projects (like Sage) don't have to. It makes a lot of sense these days to put documentation effort into pointing people at good tools for installing python, rather than maintaining our own build of python. A really similar thing is how "make configure" in sage now suggests system packages to install -- I just built sage 10.6 from source on some of my favorite Linux boxes, and the experience was great. > So +1 if it is replaced by proper documentation using a modern and standard > tool (uv?) plus a few alternatives that usual work (system installation, > pyenv). > > On Tuesday, April 1, 2025 at 8:07:07 PM UTC+2 dim...@gmail.com wrote: >> >> On Tue, Apr 1, 2025 at 10:57 AM David Lowry-Duda <da...@lowryduda.com> wrote: >> > >> > On 10:50 Tue 01 Apr 2025, Trevor Karn wrote: >> > >This is my concern.
