I've been learning Python using version 3.4. I recently started learning Web.py so have been using Python 2.7 for that, since web.py not supported in Python 3.4.  I have nose 1.3.4 module installed for both Python 3.4 and 2.7.  I need to run the nosetests command on some Python code written in 2.7 that uses the Web.py module.  However, when I type nosetests command it automatically uses Python 3.4, so is throwing an error as unable to import the Web.py module in my Python code.  Is there a way to force nosetests to use Python 2.7?  Macbook Pro running OS X Yosemite.
As @dano suggeted in his comment:
Try python2.7 -m nose instead of running nosetests.
Force Nosetests to Use Python 2.7 instead of 3.4
