Python pip install module is not found. How to link python to pip location?

No other solutions were working for me, so I tried:

pip uninstall <module> && pip install <module>

And that resolved it for me. Your mileage may vary.

Here is something I learnt after a long time of having issues with pip when I had several versions of Python installed (valid especially for OS X users which are probably using brew to install python blends.)

I assume that most python developers do have at the beginning of their scripts:

#!/bin/env python

You may be surprised to find out that this is not necessarily the same python as the one you run from the command line >python

To be sure you install the package using the correct pip instance for your python interpreter you need to run something like:

>/bin/env python -m pip install --upgrade mymodule

I also had this problem. I noticed that all of the subdirectories and files under /usr/local/lib/python2.7/dist-packages/ had no read or write permission for group and other, and they were owned by root. This means that only the root user could access them, and so any user that tried to run a Python script that used any of these modules got an import error:

$ python
Python 2.7.3 (default, Apr 10 2013, 06:20:15) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import selenium
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named selenium
>>> 

I granted read permission on the files and search permission on the subdirectories for group and other like so:

$ sudo chmod -R go+rX /usr/local/lib/python2.7/dist-packages

And that resolved the problem for me:

$ python
Python 2.7.3 (default, Apr 10 2013, 06:20:15) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import selenium
>>> 

I installed these packages with pip (run as root with sudo). I am not sure why it installed them without granting read/search permissions. This seems like a bug in pip to me, or possibly in the package configuration, but I am not very familiar with Python and its module packaging, so I don't know for sure. FWIW, all packages under dist-packages had this issue. Anyhow, hope that helps.

Regards.

As a quick workaround, and assuming that you are on a bash-like terminal (Linux/OSX), you can try to export the PYTHONPATH environment variable:

export PYTHONPATH="${PYTHONPATH}:/usr/local/lib/python2.7/site-packages:/usr/lib/python2.7/site-packages"

For Python 2.7
