用于Windows桌面的py2neo和Neo4j无法连接

我总是得到这样的错误：
File "test.py", line 13, in <module>
graph.create(alice_knows_bob)
File "C:\Python27\lib\site-packages\py2neo\database.py", line 355, in create
with self.begin() as tx:
File "C:\Python27\lib\site-packages\py2neo\database.py", line 346, in begin
return Transaction(self, autocommit)
File "C:\Python27\lib\site-packages\py2neo\database.py", line 758, in __init__
self.transaction = self.connector.begin()
File "C:\Python27\lib\site-packages\py2neo\internal\connectors.py", line 290, in begin
tx = self.pool.acquire()
File "C:\Python27\lib\site-packages\neobolt\direct.py", line 704, in acquire

File "C:\Python27\lib\site-packages\neobolt\direct.py", line 597, in acquire_direct
connection = self.connector(address, error_handler=self.connection_error_handler)
File "C:\Python27\lib\site-packages\py2neo\internal\connectors.py", line 225, in connector
return connect(address_, auth=cx_data["auth"], **kwargs)
File "C:\Python27\lib\site-packages\neobolt\direct.py", line 960, in connect
raise last_error
neobolt.exceptions.AuthError: The client is unauthorized due to authentication failure.我尝试这样连接：
from py2neo import Graph
graph = Graph()
remote_graph = Graph("bolt://neo4j:neo4j@localhost:7687/db/data/")我不知道在哪里可以找到我的真实用户名和密码。还是我做错了身份验证？

我找到答案了！
首先，确保打开http://localhost:7474/browser/并输入您在创建图形时设置的用户名neo4j和密码。如果您可以登录，则您拥有正确的用户名和密码。
接下来，确保安装了py2neo版本2.0.8。新版本不知何故在身份验证方面存在问题。
然后使用以下代码进行身份验证：
from py2neo import Graph, authenticate
graph = Graph()
# Authenticate the user using py2neo.authentication
authenticate("localhost:7474", "neo4j", "<pass>")
# # Connect to Graph and get the instance of Graph
remote_graph = Graph("http://localhost:7474/db/data/")页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
