Question

我正在运行以下命令：

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

但是得到以下错误：

No handlers could be found for logger "mongo_connector.util"<br/>
Traceback (most recent call last):<br/>

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.

注意：我正在使用neo4j 3.0，os：macosx，python：2.7 **

这似乎是由于未能将py2neo依赖项固定到特定版本而导致的错误。这个项目是使用py2neo 2.0.7编写的，但未能确定该版本，因为py2neo 3.0现在正在被拉入一些东西。

我们将很快推出3.0的更新，同时你可以通过卸载py2neo并安装2.0.7版来解决这个问题：

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
