尝试使用 py2neo 连接到 Neo4j 桌面并在我运行查询时收到“ServiceUnavailable：无法连接到任何已知路由器”

Question

I renamed the existing example database from Movies RDBM to Movies and changed the password to pwd.

from py2neo import Graph
db=Graph("neo4j://neo4j:pwd@localhost:7687", name="Movies" )

No errors for the above

db.run("MATCH (n:Movie) RETURN n").to_table()

The above fails with ServiceUnavailable: Cannot connect to any known routers

what am I doing wrong?

Answer 1

I was using WSL and Jupyter Notebooks but Neo4j was running in Windows so 127.0.0.1 was pointing to the WSL loopback and there was nothing there to receive the API calls
