Please consider next time thinking about MicroPython for this usecase, as that's exactly why there're people who think that MicroPython is interesting for "desktop" systems, not just bare-metal microcontrollers. There're too few such people so far, unfortunately, so progress is slow.
An example of a product that does this is Chef, they install their own Ruby and everything but libc into /opt/chef to completely isolate themselves from the host system. I’m told this made things *much* easier for them as they don't really have to worry at all about what's available on the host system, Chef pretty much just works.

As folks may or may not know, I'm heavily involved in pip which is probably one of the most widely used CLIs written in Python. A single file executable won't help pip, however through my experience there I
It's interesting you bring up this case of pip (and Chef), as I had similar concerns/issues when developing a self-hosted package manager for MicroPython. MicroPython doesn't come out of the box with standard library - beyond few builtin modules ("core" library), every other module/package needs to be installed individually (micropython-* modules on PyPI). That makes a package manager a critical component, and means that package manager itself cannot rely on standard library - presence, absence, of specific version (or contents of standard modules). My initial idea was to write single-file script, but we're not ready for self-sufficiency yet anyway (no SSL support, have to rely on wget), and it's a bit of chore anyway. So instead, I made a semi-automated "library subset package" (e.g. os renamed to upip_os), and all such modules comes package together with the main script: https://github.com/micropython/micropython-lib/tree/master/upip , https://pypi.python.org/pypi/micropython-upip . Then we have a script to bootstrap upip: https://github.com/micropython/micropython/blob/master/tools/bootstrap_upip.... , after which any package can be installed using upip proper. -- Best regards, Paul mailto:pmiscml@gmail.com
