It looks like the URL your are passing for Neo4j is incorrect. It should be http://127.0.0.1:7474/db/data

geosmart commented 8 years ago

@johnymontana Thank you, I changed the neo4j endpoint ,But the error still

geosmart commented 8 years ago

I reinstall neo4j_doc_manager without set --pre ,use the stable version rather than dev version.
install command:pip install neo4j-doc-manager
and now it's working fine!
thanks @johnymontana, It's just a version problem

johnymontana commented 8 years ago

Thanks @geosmart for posting this. I've updated the readme and docs to remove the --pre option for installation. This was an artifact from when there was not a stable / non-dev release in PyPI.

Head's up, I had the same error as @geosmart, re-installed without the --pre option and now (thanks for py2neo v2, am experiencing the following error:

Hi @stevenpollack, I'm facing the same issue (ImportError: cannot import name 'BindError'). Did you finally find a way to fix this?

Thanks in advance
