django项目在virtualenv中不起作用

Question

I recently installed a virtualenv and cloned an existing django project into it. When I run python manage.py runserver I'm getting the following error:

Traceback (most recent call last):
  File "manage.py", line 22, in <module>
    execute_from_command_line(sys.argv)

ImportError: Could not import settings 'application-name.settings' (Is it on sys.path?): No module named application-name.settings

when I try doing application-name/application python manage.py runserver , I get the following error:

python: can't open file 'manage.py': [Errno 2] No such file or directory

here is the application directory

application-name/
    manage.py
    application/
       __init__.py
       urls.py
       wsgi.py
       settings.py

First, rename your application-name to application_name . Dashes and Python source is just inviting problems, best not wake the dragons.

Let's assume you've put it in ~/work/application_name , ie outside your virtualenv.

If you didn't create the virtualenv with virtualenvwrapper and it doesn't have a setup.py file, then delete it (and install virtualenvwrapper ).

Create your virtualenv with virtualenvwrapper :

mkvirtualenv -a ~/work/application_name -r ~/work/application_name/requirements.txt eb_virt

-a add an existing directory as a project dir (puts it on the python path for this virtualenv). -r runs pip install -r on the argument (I'm assuming application_name/requirements.txt exists).

Instead of using the -a option (and assuming application_name/setup.py exists), you can install your package in development mode :

cd ~/work
pip install -e application_name

Either of these make ~/work/application_name part of the module search path when Python is running. Your settings file path must start relative to a directory on Python's module search path.

The DJANGO_SETTINGS_MODULE environment variable, should therefore be set to 'application.settings' .
