--user option broken? (when using relative path for PYTHONUSERBASE)

[gdamjan]

PYTHONUSERBASE=py-env pip install --user Flask fails with:

Exception:
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/pip/basecommand.py", line 134, in main

IOError: [Errno 2] No such file or directory: 'py-env/lib/python2.7/site-packages/Flask-0.10.1-py2.7.egg-info/installed-files.txt'

py-env/lib/python2.7/site-packages/ is empty so normally it can't create installed-files.txt when it didn't even create the .egg-info directory yet.

Versions are:

$ pip --version
pip 1.4.1 from /usr/lib/python2.7/site-packages (python 2.7)

$ python -c 'import setuptools; print setuptools.__version__'
0.9.8

the relative py-env path for PYTHONUSERBASE is the problem here.
just using python setup.py install --user directly (i.e. what pip does internally), I wasn't able to get it to work either.
not sure that PYTHONUSERBASE supports relative path names.

[gdamjan]

afaik it did work previously ... but if it's documented to not work, that's ok too

[qwcode]

hmm, I'll check some older pips and see.

[merwok]

PEP 370 and/or what distutils does could also be checked.

[dstufft]

I cannot reproduce this, it appears that the issue was not a pip issue to begin with and I'm assuming that at some point in the last 3 years, whoever's issue this actually was has solved it for us.

[gdamjan]

happens still for me

[dstufft]

What operating system?

[gdamjan]

ArchLinux … setuptools and pip are installed from package, but should be vanilla (and I don't see anything suspicious in the PKGBUILDs)

[pradyunsg]

This should be fixed by #4495?

[pradyunsg]

@dstufft Since #4495 is merged, can this be closed now?
