linking python project with virtualenv

Question

I have an ubuntu server 12 running as a guest in virtualbox on a windows 7 host. In a shared folder /workspace I have a python project project01. Since virtualbox has issues with creating symlinks in a shared folder I created the virtualenv in my users home directory. /home/user1/venv. I can activate the virtual environment no problem.

source ~/venv/bin/activate

but when I try to run manage.py, I get an error

~/venv/bin/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

I'm sure I'm missing a path or something, but I'm not sure exactly what path to add and to where. I tried setting PYTHONPATH in the activate script, but that didn't work. Do I need to add the path to django's core management in the activate script? I see a bunch of django directories under venv/build

Django
django-appconf
django-celery
django-celery-email
django-celery-transactions
django-debug-toolbar
django-filebrowser
django-grappelli
djangohelpers
django-imagekit
django-pipeline
django-redis
django-sslify
django-storages
django-widget-tweaks

do I need to point in there somewhere? I'm very much a django and virtualenv noob.

UPDATE It doesn't look like the packages were installed. So this is another matter entirely. Thanks for your reply. I have some other issues I need to figure out here.

I was in the virtualenv and ran pip install -r requirements.txt which only had 1 error for postgres, but I'm not using a local postgres server so that's not a huge deal. Unless that error is preventing everything from installing, then it is a huge deal.

when I check site-packages I only see the following: easy-install.pth pip-1.2.1-py2.7.egg setuptools-0.6c11-py2.7.egg setuptools.pth

and pip freeze shows me: argparse==1.2.1 wsgiref==0.1.2

the error from pip install is: Exception information: Traceback (most recent call last): File "venv/local/lib/python2.7/site-packages/pip-1.2.1-py2.7.egg/pip/basecommand.py", line 107, in main status = self.run(options, args) File "venv/local/lib/python2.7/site-packages/pip-1.2.1-py2.7.egg/pip/commands/install.py", line 256, in run requirement_set.prepare_files(finder, force_root_egg_info=self.bundle, bundle=self.bundle) File "venv/local/lib/python2.7/site-packages/pip-1.2.1-py2.7.egg/pip/req.py", line 1042, in prepare_files req_to_install.run_egg_info() File "venv/local/lib/python2.7/site-packages/pip-1.2.1-py2.7.egg/pip/req.py", line 236, in run_egg_info command_desc='python setup.py egg_info') File "venv/local/lib/python2.7/site-packages/pip-1.2.1-py2.7.egg/pip/util.py", line 612, in call_subprocess % (command_desc, proc.returncode, cwd)) InstallationError: Command python setup.py egg_info failed with error code 1 in venv/build/psycopg2

The error looks as if you do not have Django in the venv python path.

You can confirm that it is part of your venv python install using a couple of ways:

If you used PIP to install you can verify that the package is installed using pip freeze

Also check in lib/python2.7/site-packages/ of the venv there should be a django directory in there. This is the directory that is part of the PYTHONPATH for your venv.

If you cannot find the modules in there of have installed them in a different path. Then you will need to make sure that the path is part of the PYTHONPATH of the venv.
