导入数据不成功

[violahuyoujin]

网页端打开neo4j后，在pycharm中运行build_medicalgraph.py，没能导入数据，请问大家都是怎么导入的？ 我把data文件夹放在项目的venv下面了，会不会是我的项目目录有问题，找不到对应的json文件？

【补充】：我在最后面写了handler.create_graphnodes(); handler.create_graphrels() 但是在pycharm中从1走到8808后，程序报错： Traceback (most recent call last): File "E:\python_pycharm\QA_MedicalKG\venv\lib\site-packages\neobolt\addressing.py", line 132, in dns_resolve info = getaddrinfo(address[0], address[1], 0, SOCK_STREAM, IPPROTO_TCP) File "C:\Users\lenovo\AppData\Local\Programs\Python\Python36\lib\socket.py", line 745, in getaddrinfo for res in _socket.getaddrinfo(host, port, family, type, proto, flags): socket.gaierror: [Errno 11001] getaddrinfo failed

During handling of the above exception, another exception occurred:

感谢楼上，已解决问题，host地址写错了，我没修改neo4j的conf文件配置，所以默认host应该是127.0.0.1，成功导入数据

[18813055625]

请问怎么修改？

[18813055625]

@violahuyoujin 请问一下，怎么修改host？

[yan624]

@violahuyoujin 请问一下，怎么修改host？

host 就是本地的地址啊，127.0.0.1

[chenbaicheng]

@yan624 不知道是谁这样坑人的 竟然将代码修改了 少了你说的那两句代码 数据根本不会写入neo4j

1、If you are the latest version of neo4j, you also need the latest version of py2neo.

Python3- m pip install py2neo -- upgrade

2、Modify the database connection method to a new one. Graph=Graph ('bolt://localhost:7687', auth=('neo4j','lhy123')）
