我的 LateX 一直运行正常，没有出现问题。现在我刚开始我的项目，它就不再工作了，我不知道哪里出了问题。我使用 TeXmaker，并安装了 TeXLive 和 MikteX。
显示的错误信息是：

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.

You're in trouble here. Try typing <return> to proceed.

这将继续出现有关缺少字体和字母的多个错误。
我不知道发生了什么。
希望你能帮我。
你好，帕特里克。
