Mongo connector with neo4j not working

I'm running the following command:

mongo-connector -m localhost:27017 -t http://localhost:7474/db/data -d neo4j_doc_manager

But getting following error:

No handlers could be found for logger "mongo_connector.util"<br/>
Traceback (most recent call last):<br/>
  File "/usr/local/bin/mongo-connector", line 11, in <module>
    sys.exit(main())<br/>

    "vailable doc managers." % full_name)
mongo_connector.errors.InvalidConfiguration: Could not import mongo_connector.doc_managers.neo4j_doc_manager. It could be that this doc manager has been moved out of this project and is maintained elsewhere. Make sure that you have the doc manager installed alongside mongo-connector. Check the README for a list of available doc managers.

NOTE: I'm using neo4j 3.0, os: macosx, python: 2.7**

This appears to be an error caused by failing to pin the py2neo dependency to a specific version. This project was written using py2neo 2.0.7 but failed to pin that version, as py2neo 3.0 is now being pulled in a few things are breaking.

We will push an update for 3.0 soon, in the meantime you can get around this by uninstalling py2neo and installing version 2.0.7:

lyonwj@lyonwjs-MacBook-Pro-2 ~/n/mongo_demo> pip uninstall py2neo
Uninstalling py2neo-3
...
lyonwj@lyonwjs-MacBook-Pro-2 ~/n/mongo_demo> pip install py2neo==2.0.7
Collecting py2neo==2.0.7
  Downloading py2neo-2.0.7.tar.gz (251kB)
    100% |████████████████████████████████| 256kB 2.6MB/s
Installing collected packages: py2neo
  Running setup.py install for py2neo ... done
Successfully installed py2neo-2.0.7
lyonwj@lyonwjs-MacBook-Pro-2 ~/n/mongo_demo>
mongo-connector -m localhost:27017 -t http://localhost:7474/db/data -d neo4j_doc_manager
Logging to mongo-connector.log.
