Answer 1

1. 确保您已在neo4j.conf文件中添加以下行：

   apoc.export.file.enabled=true
   

   • Windows 中的文件neo4j.conf位于：C:\Users\Username\AppData\Roaming\Neo4j Community Edition

2. 编辑并取消注释#dbms.directories.plugins=plugins，如下所示

   dbms.directories.plugins=C:/Program Files/Neo4j CE 3.2.6/plugins
   

   • 如果#dbms.directories.plugins=plugins您的文件中不存在neo4j.config，那么您必须添加此行
