py2neo - 由于身份验证失败，客户端未经授权

Question

我试图从 python 3 连接到 neo4j，但我总是遇到这个错误：

---------------------------------------------------------------------------
AuthError                                 Traceback (most recent call last)
<ipython-input-20-e407bdc814a1> in <module>
----> 1 graph.create(cloves)

~/.local/lib/python3.6/site-packages/py2neo/database.py in create(self, subgraph)
    353                        :class:`.Subgraph`
    354         """
--> 355         with self.begin() as tx:
    356             tx.create(subgraph)
    357

~/.local/lib/python3.6/site-packages/neobolt/direct.py in on_failure(self, metadata)
    755         message = metadata.get("message", "Connection initialisation failed")
    756         if code == "Neo.ClientError.Security.Unauthorized":
--> 757             raise AuthError(message)
    758         else:
    759             raise ServiceUnavailable(message)

AuthError: The client is unauthorized due to authentication failure.

我的代码是：

from py2neo import Graph
from py2neo import Node, Relationship

graph = Graph("bolt://localhost:7687", user="neo4j", password="neo4j")
cloves = Node('Person', name='Cloves', born='1989')

graph.create(cloves)

我默认检查了我在neo4j上注册的用户。

我尝试了一些方法，例如创建架构师角色。即便如此，当我声明用户时，我也会遇到同样的错误。

我解决了这个问题，需要重置默认用户密码neo4j，如此处所示。
