APOC只在neo4j中部分安裝其擴展（一個程序）

Question

我下載了apoc-3.1.0.3-all.jar並將其放入我的windows7 Neo4J 3.1.1系統的插件中。

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) 

殺死計算機上的Neo4J進程，然後重新啓動服務器。

我只看到一個apoc程序列出，其他人給出關於丟失程序的錯誤。沒有neo4j日誌中的錯誤跡象。我試着解開瓶子，並重新啓動服務器。沒有運氣。

我有做

Call db.schema() 

但作爲簡單的東西沒有問題：

CALL apoc.help("help") 

將導致

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. 

什麼我做錯了，我相信它必須是我！）

$call dbms.procedures 

apoc.schema.assert apoc.schema.assert(indexes :: MAP?, constraints :: MAP?) :: (label :: STRING?, key :: LIST? OF STRING?, unique :: BOOLEAN?, action :: STRING?) (empty)

Answer 1

安裝neo4j使用安裝程序（這是最常見的）與zip或tar文件之間的差異很少。

（A）當你使用安裝安裝的Neo4j，安裝配置Neo4j的服務器來尋找plugins文件夾中的數據庫文件夾（即default.graphdb文件夾下）。

（B）當您從一個zip或tar文件安裝的Neo4j，在Neo4j的服務器將尋找在Neo4j的安裝文件夾中的plugins文件夾（例如，plugins文件夾應該是Neo4j的bin文件夾的兄弟姐妹） 。

聽起來像（A）適用於你。

Answer 2

問題是你用neo4j的windows安裝程序，這似乎不適用於插件。所以你必須使用可以正常工作的neo4j二進制文件。

這是什麼意思是，你必須要下載Windows安裝的zip版本，並按照指示在這裏：

編輯：

I think this is you case

如果不是

maybe this

Answer 3

從我記得，你必須創建一個plugins目錄到你的graph.db目錄，把apoc jar，然後重新啓動你的服務器。

否則，您可以在neo4j.conf文件中指定dbms.directories.plugins。
