没有这样的ServerPlugin：GremlinPlugin

问题描述：

我想放一些数据到Neo4j数据库使用python脚本。我认为bulbflow可以很简单的方法如何做到这一点。没有这样的ServerPlugin：GremlinPlugin

我有他们的主页和文档这个小脚本。

#!/usr/bin/python 
from bulbs.neo4jserver import Graph 
g = Graph() 
james = g.vertices.create(name="James")

但是当我运行它，我得到这个错误：

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 
    resp = self.client.create_vertex(data, keys=_keys) 
    File "/usr/lib/python2.7/site-packages/bulbs/neo4jserver/client.py", line 424, in create_vertex 
    return self.create_indexed_vertex(data, index_name, keys=keys)

    raise LookupError(http_resp)

bulbflow和Neo4j根据http://bulbflow.com/download/正确安装。 Neo4j以默认配置运行，我可以打开http://localhost:7474/。

你能帮我解决这个问题吗？

谢谢FrostyX

答

用的Neo4j 2.0启动小鬼插件不再捆绑在一起。但是，您可以轻松地自行构建和安装，请参阅。

答

是的，正如@stefan所说，从Neo4j 2起，您必须在Neo4j Server上手动安装Gremlin Plugin。但是，您可以将Neo4j与TinkerPop Rexster服务器一起使用 - Rexster随附最新的Gremlin，而灯泡可与任一服务器一起使用。
