I’ve been stuck with diagnosing this for a few hours now and thought I’d see if any pymongo experts out there have any ideas:
The following line of code:
connection = pymongo.Connection(‘localhost’, 27017)
Generates the following error:
/usr/local/Cellar/python/2.7.3/bin/python2.7 /Users/danwilson/Dropbox/Projects/mysite/app.py
Traceback (most recent call last):

mongod’s streaming output acknowledges the connection:

The solution to this problem was not good news for pip: I had to uninstall pymongo and bson, then reinstall bson, then pymongo. So it looks like the order of installation is actually important!
