I know the Anaconda installer (the Continuum Analytics one) does this
(since I've reported a bug against it for messing up user level access
to the system SQLite installation), but I don't know if the code for
that is publicly available anywhere (conda itself is open source, but
I'm not sure about the build scripts for their installers).
That said, as far as I know, just covering the discrepancy on Debian
and Ubuntu between "the system pip is patched to use --user by
default" and "~/.local/bin is not on PATH by default when using the
default shell" would cover most of the cases where this comes up.
Even short of automating the config change though, there could be
significant value in having a "check_install_config" utility that you
ran as:
pip install [--user] check_install_config
python -m check_install_config
and answered some essential fault diagnosis questions like:
- which Python version is being used?
- is there an active virtual environment?
- is it a venv environment or a virtualenv one?
- where will package installations go by default?
- where will they go with --user specified?
- where will script installations go in those two cases?
- are both of the binary install directories on the user's executable path?
Cheers,
NIck.
