Hello, thanks for a nice and clean way to run python. However, WORKON_HOME needs to be set before virtualenv_wrapper is sourced, otherwise it won't have any effect.

I think I managed to get a full 64bit python web stack on OS X 10.5.

An additional bootstrap script I have adds in the “common things” – installing them into the central location (e.g. /bin) means that when I call nose, I am calling nose that's installed against an interpreter I may not be using (e.g., 2.5 vs. 2.6). See also the postmkvirtualenv hook for virtualenvwrapper, which could be used to exec commands, rather than just change settings. I have a script which I run by hand though

I'm curious how you handle your “almost always used” tools in this virtualenv setup? In my case those are things like nose, coverage, ipython, and Sphinx. I saw the add2virtualenv command in virtualenvwrapper and thought, “Cool! I'll just install nose, et al in my default virtualenv and add them to other virtualenvs as necessary.” Alas, that doesn't work very well for packages like nose that have entry points in bin/ – the she-bang path has to be edited so that it points to the correct place, or I get import errors.

So, do you install nose in every virtualenv you create, or do you “egregiously modify” your pristine site-packages/, or is there another option I'm missing?

Comment out the “source /Library/Frameworks/Python.framework/Versions/2.6/bin/virtualenvwrapper_bashrc” line and reload everything to exclude the possibility it's a bug in virtualenv wrapper first

Hi Jesse!

Hey I am almost home. I can switch between Py 2.5 and 2.6. It seems to work well. However, there seems to be a bit of a snag with the "illegal option". The .bash_profile has been modified as you instructed to reflect the path as outlined:

>>export PATH=/Library/Frameworks/Python.framework/Versions/2.6/bin:/usr/local/bin:$PATH
source /Library/Frameworks/Python.framework/Versions/2.6/bin/virtualenvwrapper_bashrc
export WORKON_HOME=$HOME/virtualenvs<<

However, I get this message from my term window on open.
Last login: Tue Apr 7 09:11:58 on ttys002
dirname: illegal option -- b
usage: dirname path
p-ws-mac-mini:~ pw$

I had another error message before I added the (.) creating an invisible dir. I cannot glean where this is coming from.

All else appears to function as you have outlined.

Thanks for your help.

Pat

Yes, you need to be in terminal, and type that command. Everything I
outlines here is in terminal.app

OK, I'm doing things the "right" way and haven't budged past the point where I last understood what I was doing. Therefore: I ask this very simple Q what does, "Do the following â€œ. ~/.bash_profileâ€ - this sources the profile and changes your environment.", mean exactly?

Am I supposed to be in Terminal? Do I run a command? Do means many things, but here evidently for me it's ambiguous. What I gist from it is that when I run a new window in Term, I'll get references to the later version of Python, correct?

Other than that, I am on board and look forward to working with Python 2.61(2)

Thanks for your contributions!
