bokeh 0.4.1 vs virtualenv

[lebedov]

On Ubuntu 13.10 using Python 2.7.5, attempting to install bokeh 0.4.1 in a virtualenv 1.11.3 (i.e., the latest version as of the submission of this issue) fails because setup.py calls site.getsitepackages(), which currently isn't provided by the site module installed in a virtualenv. While this obviously isn't a bokeh problem, it might be nice to work around it until virtualenv is fixed.

I encountered this during PyData London 2014. In a frenzy of desperation
trying to get my laptop ready for the Bokeh tutorial I just copy/pasted
this function. You can read more here:

One fix is to get virtualenv to use the system-native version of
site.py, rather than the Python 2.6 version. Another is to figure out
why bokeh requires the Python 2.7 version of site.py, since I've
never encountered this problem with any other Python module.

This reproduces on:

• CPython 2.7.3 (native install) on Fedora 19 x64
• CPython 2.7.5 (Homebrewed install) on Mac OS X 10.8.2

On reading your pull request you did exactly this!

@lebedov @asimihsan I opened a PR to fix this issue... it is referenced above... can you try it and let me know if it fix the issue? Thanks.

The PR seems to install in a virtualenv without any problems.

From the mailing list:

Get this when trying to install from source
OS X 10.7.5

File "setup.py", line 158, in <module>
    site_packages = getsitepackages()[0]
  File "setup.py", line 83, in getsitepackages
    prefixes.append(sys.real_prefix)
AttributeError: 'module' object has no attribute 'real_prefix'

Working in a fix...

The fix seems to work, closing...
