Neo4j Python py2neo授权错误

在Windows 8.1上安装了Neo4j 2.2.3。没什么特别的。通过Neo4j开始应用程序启动服务器。没什么特别的在Neo4j.org的文档中开始使用py2neo。进入我无法解释的授权错误。日志如下。Neo4j Python py2neo授权错误

特别说明：尽管python \ script在路径中，python shell只会从C：\ python34 \ python开始。

请解释我做错了什么，可以改善。

在处理上述异常，发生了另一个异常：介绍authentication

请修复代码清单格式化。 –

cmd＆python输出格式 – Delimitry

Neo4j的2.2这是默认启用。当您第一次打开web界面（通常为http://localhost:7474/browser）时，系统会要求您设置用户名/密码。缺省值是neo4j/neo4j。

这里是如何在py2neo使用验证：

from py2neo import authenticate, Graph 

# set up authentication parameters 
authenticate("camelot:7474", "arthur", "excalibur") 

# connect to authenticated graph database 
graph = Graph("http://camelot:7474/db/data/")

参见：http://py2neo.org/2.0/essentials.html#py2neo.authenticate
