I am using Redhat Linux, and the default Python version is 2.6, so I installed Python 2.7.4 on /user/local/bin folder and modified the shell profile, so when I do:

$which python
/usr/local/bin/python

which is good.

Since I don't have super user permission of the box so I tried to install the Python libraries to a folder that I have write permission. So this is the structure of my libraries:

I created a folder called

/share/python

And under that folder, I created another folder called library where I put all the python library source folders. Say I want to install the pyes (Python Elastic Search) package. I first downloaded the source_folder, tar unzip and cd into the folder. Then I did 

python setup.py install --prefix=/share/python

Then the installation finished successfully(I have done this before) and created two library folders under 

/share/python/lib/python2.7/site-packages/

And they are 

urllib3-1.6-py2.7.egg 
pyes-0.20.1-py2.7.egg

And when I open Python. Print out sys.path to double check my customized library path has been included. This is what it said:

>>import sys
>>print sys.path
['','/usr/local/lib/python2.7/site-packages/...'..., '/share/python/lib/python2.7/site-packages']

And I am pretty sure python knows where to find the pyes and urllib3(installed as dependency). however, I still cannot load the library and the error looks like this:

>>> from pyes import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named pyes
>>> import urllib3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named urllib3

Any idea why would this happen?

Updated: You need to add those new egg folders into your path and it will work: Still not quite sure why python setup.py install created two eggs folder but don't add them to the path.

I quote:

http://peak.telecommunity.com/DevCenter/PythonEggs

.egg files are simply renamed zip files.

Open the egg with your zip program, or just rename the extension to .zip, and extract.

  • It might exist as a zipped file in Windows but in Linux I cannot see how it is zipped. However, your answer is very inspiring and I tried to add those two egg folders into the Python path and it worked now.. I am wondering why python setup.py install didn't add that for me... – B.Mr.W.

  • I've updated my answer with a link that might help you understand how eggs work – Paco Sep 25 '13 at 16:00
  • Do you know why the python install prefix command doesn't add the new created egg folders to the python path? Is there anything I can do to auto include the egg folders in this case. – B.Mr.W. Sep 25 '13 at 16:19
  • No I don't know. I actually don't really use eggs manually. The only thing I do with them is installing them from pypi. What is this egg? – Paco Sep 25 '13 at 16:27
  • Just a folder which contains the module of pyes(python elastic search) and urllib3 (one of the dependencies) – B.Mr.W. Sep 25 '13 at 16:52
  • `sudo pip install pyes urllib3` ? – Paco Sep 25 '13 at 17:06
