Question

So, I have python 2.7.3 installed and I used the Django website https://docs.djangoproject.com/en/dev/topics/install/ to install Django on my Mac OS x Mountain Lion. I used pip and virtual env, I currently am able to use Django from my current terminal but, when I open a new terminal and try say:

$ cd Django 
$ cd djangowork
$ cd firstproj
$ python manage.py runserver
Traceback (most recent call last):
  File "manage.py", line 8, in <module>
    from django.core.management import execute_from_command_line
ImportError: No module named django.core.management

This is the error I get.
I have looked online for a solution to my problem. It seems to be a common problem, dealing with the PATH. But, I cannot figure out how to fix it. Any help would be much appreciated thanks!

This is an example of what my working terminal looks like: (but if I exit out I lose everything)

(my_new_env)$ cd Django
(my_new_env)$ cd djangowork
(my_new_env)$ cd firstproj
(my_new_env)$ ls
firstproj   manage.py   testdb
(my_new_env)$ python manage.py runserver

Notice how in the second case you have (my_new_env) before the prompt, but not in the first? That’s because only in the second case have you run virtual env properly. Make sure you run source my_new_env/bin/activate before you run any python commands at the prompt. You should always have (my_new_env) before the prompt in order to make sure your environment is set up properly. You have to do this in every terminal window that you open.
