今天写一个老师的任务 在neo4j中导入json格式的知识图谱 但总是失败在第一步连接 graph = Graph(“bolt://localhost:7687”,username=“neo4j”,password = “1234”)上 贴上代码

import json from py2neo import Node, Relationship, NodeMatcher, Graph

graph = Graph(“bolt://localhost:7687”,username=“neo4j”,password = “1234”)

with open(‘微观经济学.json’, ‘r’, encoding=‘utf-8’) as file: str = file.read() results = json.loads(str) matcher = NodeMatcher(graph) for item in results: a = matcher.match(‘object’, name=item.get(‘object’)).first() if not a: a = Node(‘object’, name = item.get(‘object’)) b = matcher.match(‘object’, name=item.get(‘subject’)).first() if not b: b = Node(‘object’, name = item.get(‘subject’))

    r = Relationship(b, item.get('relation') ,a)
    graph.create(a)
    graph.create(b)
    graph.create(r)
