When I run ./manage.py run server I get the error ImportError: No module named celery

Question

I'm trying to run manage.py runserver from my virtual environment and when I do I get this message

    Traceback (most recent call last):
      File "./manage.py", line 10, in <module>
        execute_from_command_line(sys.argv)
      File "/Library/Python/2.7/site-packages/django/core/management/__init__.py", line 353, in execute_from_command_line

      File "/Users/ray/Desktop/sub_desk/myheroku/practice/src/gettingstarted/__init__.py", line 4, in <module>
        from .celery import app as celery_app
      File "/Users/ray/Desktop/sub_desk/myheroku/practice/src/gettingstarted/celery.py", line 6, in <module>
        from celery import Celery
    ImportError: No module named celery

Not only do I have celery, but it's also using python 2.7 from outside the virtenv. When I type which python while I'm in or out of the environment they both come from the same location which according to hitchhikers guide to python they should be seperate. What's going on? shouldn't it be using the python from within ythe virtual env?

then when I tried to pip install django-celery I got the following

You need to name _your_ source file something beside `celery.py` otherwise Python doesn't know to import the global `celery` package. — thebjorn, Apr 04 '17 at 16:19
Well, to be sure things are correctly setup, I would do this. Uninstall celery from main pythong. Activate virtualenv, install celery now, keep virtualenv activated and then use it. — nomad, Apr 04 '17 at 16:20

First things first, in your virtual environment install Celery:

pip install -U Celery

If you get the IOError: [Errno 13] Permission denied: as shown on your example (which means that you have this problem and you can/should sholve it by following the provided link) then use:

sudo pip install -U Celery

After that is done:

python manage.py runserver

and see if that fixes your problem.

Note:

You can set your project interpreter in PyCharm to your virtual environment

Go to File > Settings > Project: > Project Interpreter.
On the project interpreter click on the Cog icon and choose "Add Local"
Find ~/.virtualenvs/<venv_name>/bin/python
Apply then OK

Good luck :)

install celery in your virtualenv:

pip install django-celery

while in your virtualenv start the django app:

python manage.py runserver

A good check is to enter pip freeze wherever you're running this. It will print out all the installed packages.

Thanks for the response Jeremy. When I ran pip freeze I noticed that my results differed from my requirements.txt which should be identical to each other. – Ed Banes Apr 04 '17 at 16:38
Well `pip freeze > requirements.txt` should change that. It will write requirements.txt with the stuff in `pip freeze`. If you want go the other way - install everything in requirements.txt - enter `pip install -r requirements.txt` – Jeremy S. Apr 04 '17 at 16:51
