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

Question

I\'m a newbie and I needed the pySerial and feedparser module for my projects. I\'m running Mountain lion.

I followed the following tutorial so that I could upgrade

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 "", line 1, in 
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.
