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.

\expanded已经在 luatex 中可用了一段时间，但去年才添加到 pdftex 和 xetex 中，因此您需要更新与 texmaker 一起使用的 tex 发行版（或使用不使用该命令的适当的旧宏集）
