Port Python virtualenv to another system

Question

I am using many python packages like numpy, bottleneck, h5py, ... for my daily work on my computer. Since I am root on this machine it is no problem to install these package

Answer 1

You shouldn't move your virtualenv since it is essentially linked to your system python and the binary won't work on other machines.

However... you can export a list of installed packages and install them in another virtualenv through a requirements.txt file.

Basically, what I usually do with most of my projects:

# Generate a requirements file:
pip freeze > requirements.txt

On the new machine:

# This uses virtualenvwrapper, but you can do it without as well
mkproject my_project_name
git clone git://..../ .
pip install -r requirements.txt
