LaTeX 编译时出现问题：The compiler is having trouble understanding a command you have used.

编译overleaf时出现了这个错误：

 求助于 overleaf 的support staff，很快（不到1个小时）就得到了答复邮件，内容如下：

Hello,

Thanks for getting in touch!

The complete error actually looks like this:

 And the actual command that has not been defined is "XMUT@value@chairman". (Similarly for XMUT@value@appraiser i.e. the next error.)

This is because this particular template requires these values, but you have commented out the lines for chairman and appraiser in author.tex. Therefore if you re-enable these, the error messages will go away.

Even if you need to leave the names blank, you would still need to write chairman{} and appraiser{}.

I hope this helps.

Best,
LianTze

原来是在 author.tex 这个文件中的， chairman{XXXX}  和 appraiser{XXXX} 被我注释掉了。

然而，这两个值不可缺省，因此，不想要里面有内容的话，放空就可以了。

 问题得到解决，感谢林莲枝博士~
