我正在尝试使用 Lyx 模板开始撰写我的博士论文。下载链接是：https://code.google.com/archive/p/thuthesislyx/downloads
但是，当我尝试编译时，会出现许多错误main.lyx。其中一些是：
\ProcessKeysOptions { xeCJK / options }
|'''''''''''''''''''''''''''''''''''''''''''''''
| LaTeX does not know anything more about this error, sorry.
|
| Try typing <return> to proceed.
| If that doesn't work, type X <return> to quit.
|...............................................
\begin{document}
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
这些错误让我非常沮丧。有人能给我一些线索，告诉我从哪里开始吗？非常感谢！
编辑1：我.tex从文件中导出一个文件.lyx，主要错误似乎是：
! xeCJK error: "key-unknown"
!
! Sorry, but xeCJK/options does not have a key called `ItalicFont'.
!
! The key `ItalicFont' is being ignored.
!
! See the xeCJK documentation for further information.
!
! Type <return> to continue.
