	Python scripts run by python-load-file cannot use eggs installed in
	home directory
Date: Fri, 02 Dec 2011 14:39:43 +0100

When I C-c C-l a file in python-mode which contains:

import sys
print (sys.path)

the output does not include eggs in ~/.local:

['/home/rrt/Software/gnat/', '/usr/local/lib/python2.7/dist-packages/Sphinx-1.1.2-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/Jinja2-2.6-py2.7.egg', '/usr/local/share/emacs/24.0.91/etc', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/home/rrt/.local/lib/python2.7/site-packages', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.7', '/usr/lib/python2.7/dist-packages/ubuntu-sso-client']

and hence modules installed as eggs in my home directory are not found if I try to import them. If from within the session in the "*Python*" buffer I "print (sys.path)", it has changed:

['/home/rrt/.local/lib/python2.7/site-packages/pymeta2-0.0.0-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/Sphinx-1.1.2-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/Jinja2-2.6-py2.7.egg', '/usr/local/share/emacs/24.0.91/etc', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/home/rrt/.local/lib/python2.7/site-packages', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.7', '/usr/lib/python2.7/dist-packages/ubuntu-sso-client']

i.e. it seems that /home/rrt/.local/lib/python2.7/site-packages/easy-install.pth seems to be run after the python-mode buffer has already been loaded into the python process, but before control is returned to the user.

From: Reuben Thomas <rrt <at> sc3d.org>
To: 10194 <at> debbugs.gnu.org
Subject: Re: bug#10194: Acknowledgement (24.0.91; Python scripts run by
	python-load-file cannot use eggs installed in home directory)
Date: Sat, 3 Dec 2011 00:30:00 +0100

I think I've found the bug: emacs2.py's eimport overwrites sys.path[0]
while loading the given file. sys.path[0] is normally '' (the current
directory), but by default Emacs removes this entry when starting up
Python (python-remove-cwd-from-path), and so instead sys.path[0] is
some non-empty path element, and modules on it cannot be found when
loaded via eimport.

A workaround is to set python-remove-cwd-from-path to nil, but to work
properly, eimport should prepend the file's path to sys.path, thereby
allowing modules to be loaded from the current directory if
python-remove-cwd-from-path is nil, as currently that won't work
either.

This may be fixed in the current Emacs trunk, where there is a new
python.el. I'm afraid I cannot tell.

This is indeed fixed in current trunk. The new python.el allows changing 
the environment of the running shell completely and that covers this 
particular use case.
