How can I connect to my database? 我如何连接到我的数据库?
As per the error it seems like you are using a newer version of the gem than your MySQL client. 根据错误,您似乎使用的是比MySQL客户端更新的gem版本。
It says: 它说:
Could you post your MySQL gem version as well as your MySQL client version? 你可以发布你的MySQL gem版本以及你的MySQL客户端版本吗?
Upgrating your MySQL client to version 6.0.0 should fix this issue. 将MySQL客户端升级到版本6.0.0应该可以解决此问题。
