apoc报错 no procedure with the name apoc.algo.betweenness
发布于 4 个月前 作者 jackhan 332 次浏览 来自 问答

我已经下载安装了apoc,版本为3.5.0.4 Neo4j是社区版3.5.6 运行以下语句: MATCH (c:Character) WITH collect© AS characters CALL apoc.algo.betweenness([‘INTERACTS’], characters, ‘BOTH’) YIELD node, score SET node.betweenness = score RETURN node.name AS name, score ORDER BY score DESC 报错: Neo.ClientError.Procedure.ProcedureNotFound Neo.ClientError.Procedure.ProcedureNotFound: There is no procedure with the name apoc.algo.betweenness registered for this database instance. Please ensure you’ve spelled the procedure name correctly and that the procedure is properly deployed. Neo4j.conf文件中也加了这句:dbms.security.procedures.unrestricted=algo.,apoc. (变换着试了dbms.security.procedures.unrestricted=apoc.,algo. ; dbms.security.procedures.unrestricted=algo.* dbms.security.procedures.unrestricted=apoc.* )这三种情况都报同样的错误。不知问题出在哪里了?请指教!谢谢!

需要单独安装这个存储过程,安装方法,我找个链接给你

这个问题我貌似找到了答案,我安装的apoc没有apoc.algo.betweenness这个方法。我认为可能跟安装版本有关,但我不知道用哪个版本。我询问了作者,等待作者回复。

这个得去查官网api, 查到了,3.4版有apoc.algo.betweenness 存储过程,3.5以后就取消掉了这个存储过程。 3.5 之后有以algo.betweenness开头的同样功能的存储过程,详细请看下面链接 https://neo4j.com/docs/graph-algorithms/current/algorithms/betweenness-centrality/
