That happens way more often than people want to admit, and I think it's not genuine to present the tool that way. E.G, I'm on Ubuntu 20.04 on an Dell XPS, a fairly standard machine, I'll get: pyenv install 3.9 -v /tmp/python-build.20240325124651.73089 ~ Downloading Python-3.9.19.tar.xz... -> https://www.python.org/ftp/python/3.9.19/Python-3.9.19.tar.xz ... LD_LIBRARY_PATH=/tmp/python-build.20240325124651.73089/Python-3.9.19 CC='gcc -pthread' LDSHARED='gcc -pthread -shared -L/home/user/.pyenv/versions/3.9.19/lib -Wl,-rpath,/home/user/.pyenv/versions/3.9.19/lib -L/home/user/.pyenv/versions/3.9.19/lib -Wl,-rpath,/home/user/.pyenv/versions/3.9.19/lib ' OPT='-DNDEBUG -g -fwrapv -O3 -Wall' _TCLTK_INCLUDES='' _TCLTK_LIBS='' ./python -E ./setup.py build running build running build_ext ... etc There are obviously binaries for this Python, since I can apt install it and I didn't specify the minor version. But by default it downloads the source, and compiles it. On top of that it will use a shim which comes with its own world of possible pain. Again, I don't want to bash on pyenv. But I do want to lower people's expectations. It's a tool for experts, not beginners.

I’ve quite literally never seen it download a pre-compiled Python - I didn’t actually know it had that functionality, and have been using it for probably a decade.

  Ditto. I had no idea that it ever looked for a pre-compiled version.

Actually, I'm pretty sure that binaries for Python 3.9 aren't available on Ubuntu 20.04 without adding an apt repository to get them from, so your statement that you "can apt install it" isn't entirely correct in this case - by default, binaries aren't available, and therefore pyenv has to compile Python 3.9.

  Just tried, I get the same result with 3.7, 3.8, 3.10 and 3.11.
