ImportError: No module named connection

[joegoggins]

Apologies if this a total python newb issue rather than a mongoctl issue. I'm seeing the following behavior, any ideas on how to resolve?

After uninstalling and reinstalling python (2.7.9) via Homebrew on OS X 10.10 and trying pip installs with sudo and without, I keep getting this error:

Traceback (most recent call last):
  File "/usr/local/bin/mongoctl", line 48, in <module>
    from mongoctl import mongoctl
  File "/usr/local/lib/python2.7/site-packages/mongoctl/mongoctl.py", line 38, in <module>
    import objects.server
  File "/usr/local/lib/python2.7/site-packages/mongoctl/objects/server.py", line 21, in <module>
    from pymongo.connection import Connection
ImportError: No module named connection

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. https://github.com/shinken-monitoring/mod-mongodb/pull/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!
