How to install neo4django in virtual environment

Question

I receive the error below when trying to install neo4django in my virtual environment. Not sure what the problem is. The server is running on my machine and py2neo works with the restful api, but not neo4django.

I'm running ubuntu 12.0.4 with the latest version of neo4j installed (1.9-M01) and jdk 1.7 (openjkd) installed with JAVA_HOME pointing to: /usr/lib/jvm/java-7-openjdk-amd64

neo4jrestclient==1.7.0

Any help is greatly appreciated!

From what I can see, your installation is fine. The problem is the version of Neo4j.

So far, we only support Neo4j 1.6-1.8. While I try to support all major releases in use, I typically extend support for milestones closer to a general release. For example, I didn't extend support to Neo4j 1.8 until it hit milestone 6.

Is there a particular reason you're using 1.9M01, or would the most recent stable release (1.8GA) suffice?
