Django not finding apps in virtualenv when using manage.py syncdb

My problem is in getting manage.py syncdb to run within a virtualenv.

It was working fine at on开发者_如何学运维e point, but seems to have broken sometime around when I installed South and updated pip and distribute.

Anyways, when the virtualenv is activated, I can import apps fine within the interactive interpreter. Running through mod_wsgi, the apps are imported as well, and the site can run.

When I run manage.py syncdb, it fails to find any app in INSTALLED_APPS that is in my virtualenv. It picks up system-installed apps fine, but fails when it tries to import virtualenv only apps.

Hi This is an old question, but saw its not answered. Not sure what you are attempting to do, but there are basically two modes you can use virtualenv,

1. For development, to create self-contained environments
2. For deployment, to create self-contained environments

In the first case, you need to first Activate your virtualenv with source venv/bin/activate, for when you deploy, you need to ensure that the virtualenv is activated for your website code. Personally i prefer the following approach to ensuring your path is set correctly. (I also add this to my manage.py when doing development, so i dont have to worry about activating the environment first.

Modified manage.py

#!/usr/bin/env python
import os.path

# Cater for Virtual env, add to sys.path
pwd = os.path.abspath(os.path.dirname(__file__))
project = os.path.basename(pwd)
new_path = pwd.strip(project)
activate_this = os.path.join(new_path,'venv','bin','activate_this.py')
execfile(activate_this, dict(__file__=activate_this))

from django.core.management import execute_manager
try:
    import settings # Assumed to be in the same directory.
except ImportError:
    import sys
    sys.stderr.write("Error: Can't find the file 'settings.py' in the directory containing %r. It appears you've customized things.\nYou'll have to run django-admin.py, passing it your settings module.\n(If the file settings.py does indeed exist, it's causing an ImportError somehow.)\n" % __file__)
    sys.exit(1)

if __name__ == "__main__":
    execute_manager(settings)

This works, due to how i structure my projects, you would have to change it to your directory structure. My projects are structured like so:

TopLevelDir
|
|- Project DIR
|- venv
|- requirements 
|- deployment configs

I have a simple solution to this

Just launch manage.py from the python in the bin of your virtual environment.

So say your python is here /home/tom/environments/my_env/bin/python you could launch manage.py like so:

/home/tom/environments/my_env/bin/python manage.py syncdb

then just create a symlink to the virtual environment's python inside your django project and call it env_python then you can do this:

./env_python manage.py syncdb
