ImportError: No module named connection about mongoctl

[asiebert]

We are using the mongoctl cookbook to install it, and I just faced the same error when bootstrapping a new server. The issue can be easily reproduced in a fresh virtualenv though:

$ virtualenv venv

$ source venv/bin/activate

(venv)$ pip

(venv)$ pip install mongoctl

It would appear pymongo 3.0.1 is installed (which is the latest available) regardless of what is specified in the current setup.py.
Downgrading pymongo to 2.8 is enough to fix the issue: pip install pymongo==2.8

Note: it seems the pymongo.connection.Connection indeed disappeared in pymongo 3.0, in favor of pymongo.MongoClient (e.g. shinken-monitoring/mod-mongodb#7)

Hi,

The issue has been fixed and a newer version has been pushed to pypi 0.7.81 which has the proper pymongo dependency. Sorry for the trouble but pypi was acting weird for some reason. It was downloading version 0.7.7 while 0.7.8 was available so i had to re-upload 0.7.8 under a different version 0.7.81 so it would become the default.

Cheers!
