How to configure a virtual environment that doesn't require sudo?

Question

In my Ubuntu 12.04 machine, the installation of pip requirements is asking me for sudo permission every time it attempts to install. How would I override this, as this is terrible for my working environment to install things globally instead of inside the venv?

Note: I did not setup the venv using sudo.

Thanks to @MartijnPieters, I found a workaround:

Running

~/.virtualenvs/myapp/bin/pip install -r requirements.txt

Instead of just

pip install -r requirements.txt
