I'm receiving the following error when trying to open bpython in my terminal and I'm not sure how to fix it. I'm new to Python and so I think I may not understand the package system correctly. I'm not sure if there is a conflict from having easy_install and pip both installed.
Traceback (most recent call last):

Hah, I think I can answer this. When we released the last version of bpython I got confused in the PyPi web interface and accidentally removed the 0.12 tarball from the index replacing it with 0.13.
Your requirement was to have exactly bpython==0.12 fetched from the index which was sadly not there (it has been corrected by now).
