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.
但它编译并显示目录，所以这似乎只是一个技术问题。
当我删除该行时\usepackage[palatino]{quotchap}问题就消失了，所以我认为这是该包的问题？
任何帮助表示感谢
