Last night i was able to upload packages to devpi. I was able to retrieve dependencies from devpi. Now I cannot do anything with confidence that it will work. If I try to install packages (like shutilwhich) it fails. If I try to build shutilwhich and upload to my repository, it fails. So, devpi is absolutely useless at the moment and a major factor blocking my working day. I didn't do anything useful today and this is definitely annoying. So, apart of my rant (which is not constructive), I have a constructive suggestion: Pin package versions numbers in setup.py. These package versions are known to work, because all test cases pass (or should!). People using devpi simply create a minimalist virtualenv and run setup.py, which automagically install the correct numbers which are known to work properly.
