Ich möchte einige Daten zu Neo4j Datenbank mit Python-Skript. Ich denke, bulbflow kann eine einfache Möglichkeit sein, das zu tun.Kein solches ServerPlugin: GremlinPlugin
Ich habe dieses kleine Skript von ihrer Homepage und Docs.
#!/usr/bin/python
from bulbs.neo4jserver import Graph
g = Graph()
james = g.vertices.create(name="James")
Aber wenn ich es laufen lasse, erhalte ich diese Fehlermeldung:
Traceback (most recent call last):
File "./bulb.py", line 4, in <module>
james = g.vertices.create(name="James")
File "/usr/lib/python2.7/site-packages/bulbs/element.py", line 565, in create

bulbflow und Neo4j richtig nach http://bulbflow.com/download/ installiert ist. Neo4j läuft mit Standardkonfiguration und ich kann http://localhost:7474/ öffnen.
Können Sie mir bitte bei diesem Problem helfen?
Danke, FrostyX
