I've used pew [0] a couple of times, which feels like it works quite well. It is a nice alternative to virtualenvwrapper. However, my personal struggle with Python projects is when I work on projects that I also use my self on a daily basis. I have a tool that I wrote for automating some administrative stuff at work, and every so often I make some minor fixes and updates. So, I both use it and develop it at the same machine. I've never figured out how to properly do this with a virtualenv. I.e., I want the tool, say "mypytool", to be available and run the most recent version in any shell. At the same time, I would prefer not to install the requirements globally (or for that matter, at the user level). I would love to hear some suggestions on how to solve this use case.
