I'm thinking of trying out Mojo in large part because they say they're aiming for Python compatibility, and they produce single-file executables.
Previous to that I was using PyInstaller but it was always a little fragile (I had to run the build script a couple of times before it would successfully complete).
Currently I'm using pipx and Poetry, which seems pretty good (100% success rate on builds, and when my 5-line build script fails it's because of an actual error on my part).
Which is a round-about way of asking everyone:
Does anyone have any other good way(s) to build single-file executables with Python?
