这个bug可能是由于Mysql自身的问题产生的,如果知道Mysql的版本号可能更好定位问题,我搜索了相关文档描述了这个问题可能在Mysql5.6以及Mysql5.6以下版本产生,我的Mysql环境是8.0所以已经没有了innodb_large_prefix这个参数。
当这个参数为OFF时,会出现表前缀无法超过767个字符的问题,但是塞拉斯的前缀是超过了767的。需要将该参数设置成ON才可以继续下一步
可以尝试使用命令查询innodb_large_prefix这个参数是否为ON

show variables like '%innodb_large_prefix%';

如果为OFF的话,执行如下命令可以解决该问题

set global innodb_large_prefix=on;

我会在下个版本调整这个地方,看看能否将前缀缩小到767以内。

好的,感谢解答,我的MySQL版本确实是5.6,我将按照你的建议操作一下,不行的话我再将MySQL更新至8.0以上,感谢Thanks♪(・ω・)ノ
