It looks like I have multiple versions of python installed which are causing
problems while installing modules using pip. Even after installing django
manage.py runserver shows error regarding unable to find django.core something
something. How to solve this problem? Please help!!


Answer: python -v is for 'verbose':

    
    
    -v     : verbose (trace import statements); also PYTHONVERBOSE=x
             can be supplied multiple times to increase verbosity
    

Note it is **lowercase**

`python -V` will give you the version. (uppercase v)
