我正在尝试使用Gollumn Wiki,所以我可以编辑我的GitHub Wiki,但我似乎无法让它工作.
我在Ubuntu 11.10,64位上.
我也尝试过使用Ruby 1.9,也是同样的错误.
我为我的项目克隆了我的GitHub Wiki git存储库,启动了Gollum,这是我收到的错误:
Redcarpet
:Module的/ undefined方法`new'的NoMethodError
完整的堆栈跟踪是:
:public is no longer used to avoid overloading Module#public, use :public_folder instead

(假设你可以神奇地翻转neo4j中的关系方向)
哪个会更快？
START a=node(345)
MATCH (a)<-[:foo]-(b)<-[:bar]-(c)
RETURN c
要么
START a=node(345)
MATCH (a)-[:foo]->(b)-[:bar]->(c)
RETURN c
或者无关紧要,在引擎盖下,你可以向任何一个方向移动？
