First, Skip, I *only* care about the default behavior. There's already
a way to do it differently: PYTHONPATH. So, Fred, I think what you're
arguing for is to drop this feature entirely. Or is there some other
use for a new way to allow users to explicitly add something to
sys.path, aside from PYTHONPATH? It seems that it would add more
complexity and I can't see what the value would be.
PYTHONPATH is lacking one feature which is important for lots of
packages and setuptools. The directories in PYTHONPATH are just added to
sys.path. But setuptools require a site package directory. Maybe a new
env var PYTHONSITEPATH could solve the problem.
We don't need another setup variable for this. Just place a
well-known module into the site-packages/ directory and then
query it's __file__ attribute, e.g.
site-packages/site_packages.py
The module could even include a few helpers to query various
settings which apply to the site packages directory, e.g.
site_packages.get_dir()
site_packages.list_packages()
site_packages.list_modules()
etc.
As I've said a dozen times in this thread already, the feature I'd like
to get from a per-user installation location is that 'setup.py install',
or at least some completely canonical distutils incantation, should
work, by default, for non-root users; ideally non-administrators on
windows as well as non-root users on unixish platforms.
The implementation of my PEP provides a new option for install:
$ python setup.py install --user
Is it sufficient for you?
Just in case you don't know...
python setup.py install --home=~
will install to ~/lib/python
The problem is not getting the packages installed in a non-admin
location. It's about Python looking in a non-admin location per
default (as well as in the site-packages location).
