python pip trouble installing from requirements.txt

Question

I\'ve had great luck with pip in the past, but working at installing some stuff in a venv on is giving me some headaches. I keep getting errors like No distributions at

Answer 1

I had this problem but with a different cause - I had an old version of virtualenv. Before version 1.7 you had to specify the option --no-site-packages when you create the virtual environment to not include global packages.

Two options to fix this, either upgrade your virtualenv:

sudo pip install virtualenv --upgrade
virtualenv venv

Or use the old one with the no-site-packages option:

virtualenv venv --no-site-packages

That fixed my requirements.txt file.
