Newbie: install issues

[Seven Reeds]

Hi,

I am new to python and MySQLdb1 but i am not new to linux or programming. My eventual goal is to use Django and MySQL for a RESTful app. I am on a "managed" RedHat CloudLinux Server release 6.5. I DO NOT have root or sudo access on this machine. Python 2.6.6 is native on the machine. I have downloaded and installed "pip" into my login account. I installed the current Django using pip as well as mysql-python.

Django seems to have installed correctly. I'm not sure about mysql-python though for two reasons: 1) when I tried the Django tutorial that would initialize the databases it fails saying that "django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb".

The pip install of mysql-python looked like:

$ pip install mysql-python

The Django error trace is:

ideas?

Doh! this always happens. I write the request then find the answer.

I scrubbed my "local" python install and reinstalled everything. This time I found that you can user the "--user" clause when installing

pip install --user mysql-python

and something similar for django and that looks like it worked
