Fix Virtualenv compatibility

[migurski]

pip install gspread fails inside virtualenv with a space in parent directory name. I’m running Python 2.7.5 on Mac OS 10.9, and when I attempt to install using pip, gspread tries to install itself in /Library/Python/2.7/site-packages where it encounters a permission failure. I can still correctly install gspread from the Git repo, using python setup.py install.

Steps to reproduce:

1. mkdir "/tmp/foo bar" (note space in the name)
2. cd "/tmp/foo bar"
3. virtualenv venv-foo
4. source venv-foo/bin/activate.csh (I use tcsh)
5. pip install gspread

Here's a log of the error.

When the parent directory has no space in its name, pip installs as expected:

1. mkdir /tmp/foo-bar
2. cd /tmp/foo-bar
3. virtualenv venv-foo
4. source venv-foo/bin/activate.csh
5. pip install gspread now works.

Once installed, works beautifully. Thank you.

@migurski Thanks for reporting the issue and sorry for the two years delay in reply.

I don't think the problem is related to gspread, though. In the linked install log, the pip version is /usr/local/bin/pip which looks like a system-wide installation. I'm not sure about the exact reason behind this particular failure, but similar permission-related errors have been reported on StackOverflow.

A space in a directory name is another known issue. It is also unrelated to gspread.
