OpenStack Clients on Mac OS Yosemite

Clearly I haven't written a blog post recently enough. That must explain the negative karma behind running into a tricky problem.

As we all know, "pipin' ain't easy". I held off upgrading to Yosemite for a long time so as not to break my functioning Mac with OpenStack clients. However, I found time and reason to upgrade last weekend and had helped several others through the Mac client solutions a week prior.

Alas, it was not to be a sweet journey for me. I endedup with the dreaded xmlrpc_client issue. Some coworkers determined that you could resolve this by uninstalling "six" and then reinstalling "six". Unfortunately that doesn't really work. A "sudo -H pip uninstall six" did do the right thing, but "easy_install six" never succeeded. And I should note the reason that six in pip doesn't work in the first place is that the Mac OS Yosemite itself has a downrev version of six installed.

The trick, at least in my case, was to "type -a easy_install" and note that there are two versions of easy_intall. Pick the second one and you are off to the races. Here's the steps if you are still reading:

dmbp:~ dmedberry$ sudo easy_install six #fails
