所以,我在mac-osx上使用python3.2和灯泡,使用rexster和orientdb.细节:
orientdb - 从他们的页面下载标准
〜/工作区/ orientdb社区-1.7-RC1
运行服务器, ./bin/server.sh
database - orientdb database~/databases/orientdb/dev-db-01
rexster - 来自github git clone的标准结账git://github.com/tinkerpop/rexster.wiki.git~/ workspace /
配置/ rexster.xml:
...... true dev-db-01 orientgraph local:* */databases/orientdb/dev-db-01 admin admin tp:gremlin
Python代码:
from bulbs.rexster import Graph from bulbs.config import Config config = Config("http://localhost:8182/dev-db-01/", username="admin", password="admin") g = Graph(config)
问题:

我认为 python代码配置中的url是不正确的(我已经尝试了各种变体).但我不知道; 如果我保持rexster.xml不变并只使用标准图形构造函数,它就可以工作; 但那是一个问题,因为它没有向我想要的orientdb数据库添加节点,dev-db-01,它将它们放在默认数据库中.因此,为了确保我连接到正确的数据库,除了我创建的orientdb数据库之外,我禁用了所有数据库.
如何正确连接?
