python - 没有这样的 ServerPlugin : GremlinPlugin

Question

我想使用 python 脚本将一些数据放入 Neo4j 数据库。我想bulbflow可以很简单地做到这一点。

我从他们的主页和文档中获得了这个小脚本。

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

但是当我运行它时，我得到了这个错误:

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)
  File "/usr/lib/python2.7/site-packages/bulbs/neo4jserver/client.py", line 1054, in create_indexed_vertex

    raise LookupError(http_resp)

bulbflow 和 Neo4j 已根据 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？

谢谢你，FrostyX

从 Neo4j 2.0 开始，不再捆绑 gremlin 插件。但是，您可以轻松地自己构建和安装它，请参阅 https://github.com/neo4j-contrib/gremlin-plugin .
