Installing Bio Python in local Ubuntu server

I am trying to install biopython in my ubuntu server but hit the wall several times with this error message:
Cannot fetch index base URL

I checked my pip version using the following command:

$pip --version and the output is 1.5.4.

I googled little bit about it and saw this nice post at

I followed this exactly and installed pip version 1.2.1 and checked the path where it is installed. For instance my earlier pip version is not over written and it is installed in a separate place, then calling pip will still use it from the previous location.

So, I did the following:

/usr/local/bin/pip install biopython and it worked like a charm.


  1. good information so that i can install the bio-python in future if its needed , I like the way you write everything in a blog mam it is helpful for so many of us....
