How to deploy python webapp with dependencies using virtualenv?

Question

I am looking for a way to automate the deployment of Python web applications to a server. I would like to use virtualenv to create a clean environment for this application.

However, I am wondering how to manage dependencies when deploying to a server?

In development, I have virtualenv in which I install external libraries using pip, so I'm looking for a way to automatically install these dependencies during production?

thank you for your time

With pip, you can create a requirements file:

$ pip freeze > requirements.txt

Then on the server, install all of them:

$ pip install -r requirements.txt
