python pip trouble installing from requirements.txt

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 all found for somepackage Storing debug log for failure in /root/.pip/pip.log

Could not find any downloads that satisfy the requirement somepackage

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-RjqjFW/psycopg2

I know these packages are installed on the main system, but its like they won't work on the venv. How do you all get around this problem? It's been a long day and I just don't understand what the problem is, especially because they work on my local system, they work on the main python install on my remote system, but not in the venv for some crazy reason. Any ideas?

Here is the requirements, I thought it was alittle intense for django, but thats what pip freeze > requirements.txt gave me

Had a similar issue but the above method didn't work for me. Clarified it with a rather simpler solution:

(venv) $ pip install --upgrade -r requirements.txt

UPDATE: This command upgrades all packages that have been explicitly listed in your requirements.txt file.

Your requirements.txt file is just a list of pip install arguments placed in a file. They are used to hold the result from pip freeze for the purpose of achieving repeatable installations. In this case, your requirements.txt file contains a pinned version of everything that was installed when pip freeze was run.
