與neo4j Gremlin服務器

我想通過tinkerpop使用gremlin-server。我無法使用neo4j啓動gremlin服務器。與neo4j Gremlin服務器

該文件說。

請注意，TinkerPop在其發行版中不包含Neo4j依賴項。要使用此文件，請確保Neo4j的依賴安裝到小鬼服務器的路徑與gremlin-server.sh -i org.apache.tinkerpop的Neo4j-小鬼3.yz

我已經安裝使用的Neo4j的，小鬼：安裝，因爲-i據說已被棄用。

不過，我收到以下錯誤，在下面的命令

.\bin\gremlin-server.bat .\conf\gremlin-server-neo4j.yaml

什麼在你的'GREMLIN_SERVER_INSTALL/ext'目錄中？你看到neo4j目錄和相關文件嗎？另外，你提到使用'gremlin-server.sh'，但也指定使用'.bat'開始 - 這是一個Windows環境或其他？ –

我正在使用Windows環境。我無法在/ ext文件夾中找到neo4j目錄。但是這些文件安裝在Gremlin控制檯中。修復了從控制檯目錄到服務器目錄的簡單複製。感謝您的指導。 –

你是說'gremlin.bat：install'把neo4j jar放在'GREMLIN_SERVER_INSTALL/ext'以外的目錄中嗎？ –

:install在控制檯命令。

install是服務器命令。 -i也仍然有效。
