Neo4j Python py2neo授權錯誤

Question

在Windows 8.1上安裝Neo4j 2.2.3。 沒什么特別的。 通過Neo4j啟動應用程序啟動服務器。 沒有什么特別的東西開始使用py2neo，就像Neo4j.org上的文檔一樣。 進入授權錯誤我無法解釋。 記錄如下。

一個特別的評論：盡管python \\ script在路徑中，但python shell只能從C：\\ python34 \\ python開始。

請解釋我做錯了什么，可以改進。

在處理上述異常期間，發生了另一個異常：

Answer 1

neo4j 2.2引入了默認啟用的身份驗證 。 當您第一次打開Web界面（通常是http://localhost:7474/browser ）時，系統會要求您設置用戶名/密碼。 默認為neo4j / neo4j。

以下是如何在py2neo中使用身份驗證：

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/")

請參閱： http ： //py2neo.org/2.0/essentials.html#py2neo.authenticate

Answer 2

就我而言，這很有用。

在libexec / conf下，找到neo4j.conf文件夾。

刪除“dbms.security.auth_enabled = false”之前的＃
