Question

I am trying to connect to neo4j from py2neo:

    from py2neo.server import GraphServer
    server=GraphServer()
    server.start()

At this stage when I check the logs I see that the server is up and running:

    2016-06-10 09:41:09.928-0600 INFO  Initiating metrics..
    2016-06-10 09:42:01.288-0600 INFO  Successfully started database
    2016-06-10 09:42:01.305-0600 INFO  Starting HTTP on port 7474 (40 threads available)

  2016-06-10 09:42:03.085-0600 INFO  Remote interface ready and available at http://0.0.0.0:7474/

But in ipython I get the below error:

       TypeError                                 Traceback (most recent call  last)
<ipython-input-46-5e4be8f41f99> in <module>()
 ----> 1 server.start()

  /usr/local/lib/python2.7/dist-packages/py2neo/server.pyc in start(self)
190             uri = None
191             kwargs = {}
--> 192             for line in out.decode("utf-8").splitlines(keepends=False):
193                 if line.startswith("Using additional JVM arguments:"):
194                     kwargs["jvm_arguments"] = shlex.split(line[32:])

 TypeError: splitlines() takes no keyword arguments

If any more info is needed please feel free to ask for it.

Answer 1

您使用的是哪个版本的Python，Neo4j和py2neo？它们是否在py2neo.org上列为支持的版本？

Answer 2

作为一个解决方法，我一直在使用./bin/neo4j start从linux本身启动Neo4j，即使我从linux注销也会一直启动。
