neo4j community 4.4.21配置apoc4.4.0.18无法成功

[limaoSure]

我根据教程对我的neo4j4.4.21配置了4.4.0.18，并且在conf文件里面设置了对应的参数，但在neo4j环境下无法检测apoc版本，并且显示：
Neo.ClientError.Statement.SyntaxError
Unknown function 'apoc.version' (line 1, column 8 (offset: 7))
"RETURN apoc.version() AS version"
请问是我的apoc版本下载错了吗？

Hi there! Thanks for writing in. I haven't been able to reproduce, so would just like to confirm some things.

The APOC jar is under plugins and you have restarted your database?

If you query: 'SHOW FUNCTIONS', do you see any APOC functions at all?

What does your config look like? and are there any errors in the log file on db start?

Thanks :)
