Character set 'utf-8' is not a compiled character set and is not specified

我在terminal登入mysql时候，如报下面错误：Mysql提示说你要在/usr/share/mysql/charsets/Index.xml文件将缺失的编码集加入，但是我检查后发现在Index.xml文件中有我需要的编码集。

这个链接给出答案对我有效

Character set 'utf-8' is not a compiled character set and is not
specified in the '/usr/share/mysql/charsets/Index.xml' file

当出现“Character set ‘utf-8’ is not a compiled character set and is not specifie”的错误时，将mysql安装目录下的my.ini文件的default-character-set=utf-8更改为default-character-set=utf8即可.
简单来说就是将”utf-8”更改为”utf8”即可。
