報(bào)錯(cuò)信息：
從graph.run這里報(bào)錯(cuò)，報(bào)出一個(gè)JSon相關(guān)的錯(cuò)誤，百思不得其解。
Traceback (most recent call last):

解決方法:
需要加上一個(gè)name=“neo4j”，才能成功，如下
graph = Graph("http://localhost:7474",user= "neo4j",password = "zhang123",name="neo4j")
或者這樣文章來(lái)源：http://www.zghlxwxcb.cn/news/detail-502414.html
graph = Graph("http://localhost:7474",auth=("neo4j","zhang123"),name="neo4j")

from py2neo import Graph

cypher = "create (n:person {name : '老大',age : 18,length : 168})"
graph.run(cypher)
