PIP: Installing only the dependencies

python pip virtualenv distribute
muhuk picture muhuk · Feb 23, 2010 · Viewed 23.7k times · Source

I have a script that creates a virtualenv, installs distribute and pip in it and then optionally clones a git repo.

Now I have the project I will be working on, installed. But its dependencies are not installed. How can I make pip install all the dependencies as if I have issued a pip install MyApp?

EDIT: Appareantly my question is a duplicate of this one.

Not exactly sure but pip install -e . seems to do what I want without too many extra stuff lying around. I'd prefer if my code wasn't linked from site-packages though.

If your dependencies are defined in the setup.py file, you can first dump them to an external file using:

python setup.py egg_info

This will list all your dependencies in YOUR_PROJECT.egg-info/requires.txt file. Then you can install them using pip:

pip install -r *.egg-info/requires.txt
