APOC仅将其扩展程序部分安装在neo4j中(一个过程) [英] APOC is only partially installing its extension in neo4j (one procedure)

问题描述

我下载了apoc-3.1.0.3-all.jar并将其放在Windows7 Neo4J 3.1.1系统的插件中.

I downloaded apoc-3.1.0.3-all.jar and placed it in the plugins for my windows7 Neo4J 3.1.1 system.

C:\Users>java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

杀死计算机上的Neo4J进程，然后重新启动服务器.

Killed the Neo4J process on the computer, and then restated the server.

我只看到一个列出的apoc程序，其他的给出了关于缺少该程序的错误. neo4j日志中没有错误迹象.我尝试解除对jar的阻止，然后重新启动服务器.没有运气.

I am only seeing one apoc procedure listed, others give an error about missing procedure. ThereNo sign of errors in the neo4j log. I tried unblocking the jar, and restarting the server. No luck.

我没问题

Call db.schema()

但是很简单:

CALL apoc.help("help")

将导致

There is no procedure with the name `apoc.help` registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.

我在做错什么，我想一定是我！)

What am I doing wrong, I assume it must be me!)

$call dbms.procedures

推荐答案

使用安装程序(最常见)安装zip和tar文件与安装neo4j之间的差异(文献记载很少).

There is a poorly documented difference between installing neo4j using an installer (which is most common) versus from a zip or tar file.

(A)使用 installer 安装neo4j时，安装程​​序将neo4j服务器配置为在 database文件夹中查找plugins文件夹(即，在default.graphdb文件夹).

(A) When you install neo4j using an installer, the installer configures the neo4j server to look for the plugins folder in the database folder (i.e., under the default.graphdb folder).

(B)从zip或tar文件安装neo4j时，neo4j服务器将在neo4j安装文件夹中查找plugins文件夹(例如，plugins文件夹应为neo4j的同级bin文件夹).

(B) When you install neo4j from a zip or tar file, the neo4j server will look for the plugins folder in the neo4j installation folder (for example, the plugins folder should be a sibling of the neo4j bin folder).

听起来像(A)适用于您.

It sounds like (A) applies to you.
