Given a module on pypi, is there a way to introspect the module and show all dependencies?

Question

For example, I am looking for a command line snippet to list all dependencies of a python module e.g. http://pypi.python.org/pypi/django-celery given the URL. Does one exist ?

Answer 1

I would use a combination of virtualenv and pip to do the job. The snippet would look sth like this:

virtualenv <path_to_a_new_env> --no-site-packages
<using this virtual env> && pip install <url or package name>
<using this virtual env> && pip freeze
---
<using this virtualenv> - source bin/activate on Linux scipts/activate.bat on linux

The problem is that you this would only list dependencies, but not versions if any specific are required.
