lib path is hardcoded in backwardcompat/__init__.py:home_lib()

[haxwithaxe]

library path in home_lib() in backwardcompat/init.py is hardcoded to 'lib' this breaks when the system default is lib64.
pip install --target /home/user/twitter-pip twitter
displays the problem.

the directroy created during install is /tmp/tmpXgpY70/lib64/

i don't have a good fix but i did check for the 'ARCH' environmental variable and set the lib directory accordingly in the home_lib() function.

in all of the cpython's, the home scheme literally does just use the lib/python path.
http://docs.python.org/3.3/install/#alternate-installation-the-home-scheme

this is arch linux?

we do have a pip.locations.distutils_scheme method we could use for this.
maybe you can try that on arch and confirm it works (set home=True)

where am i supposed to use "pip.locations.distutils_scheme"? i just picked a random module and directory to try the --target argument.

[qwcode]

let me work up a pull tomorrow, and you can try it.

merged the pull request for this.

I can still reproduce this using:

pip install --target . lxml

on

• CentOS 6.7
• python.x86_64 2.6.6-64.el6
• pip 7.1.2

Exception:
Traceback (most recent call last):
File "/usr/lib/python2.6/site-packages/pip/basecommand.py", line 211, in main

for item in os.listdir(lib_dir):
OSError: [Errno 2] No such file or directory: '/tmp/tmpTCtSpy/lib/python'

But the lib64 variant is present:

ls -R /tmp/tmpTCtSpy/

/tmp/tmpTCtSpy/:
lib64

/tmp/tmpTCtSpy/lib64:
python

/tmp/tmpTCtSpy/lib64/python:
lxml lxml-3.4.4-py2.6.egg-info

...

[haxwithaxe]

is the lib path in home_lib() in backwardcompat/__init__.py still hardcoded to 'lib'? this ticket was specific to a code change not a specific runtime error.

Sorry, I wasn't sure where to post this. At first I thought it might be a regression (and it still may be),
but I think that we'll continue the discussion on this Github issue.
