If you are interested in managing the project that would isolate from other python projects then you can use virtualenv. 

With this you can run virtual installations on your developer machine.


To install just pip it:
  
         pip install virtualenv


To create any environment just type this;
   
 virtualenv [environment_name]



To activate any off the environments you have created type;

 source [environment_name]/bin/activate

To deactivate the virtualenv:
   
   $ deactivate

To install virtualenv wrapper:

   $Pip install virtualenvwrapper
