\maketitle 错误 - 控制序列未定义

Question

.tex我从一位同事那里继承了一份文档.cls，其中包含用于准备课程大纲的支持文件。提供该文件的人告诉我，他们运行它没有问题。但是，当我下载所有必要的文件并按下编译时，我看到了“未定义的控制序列。\maketitle”错误。我查看了该.cls文件以查看是否有任何明显的问题，但我找不到错误的来源。以下是源代码的一个最小工作示例：

该.cls文件定义\university、\department等。

以下是文件中的定义块.cls：

我的问题是，我似乎无法弄清楚为什么编译器会抛出“未定义的控制序列。\maketitle”错误。我查看了许多具有类似主题标题的帖子，但尝试了几种建议的修复方法都没有帮助。谢谢。更新：如果有助于解决问题，可以从此处下载该.tex文件和文件：.cls

https://www.dropbox.com/sh/n86yao7ejpbz800/AABdQXHRNqC0WfxuOER2tozqa?dl=0。

该代码确实创建了一个 .pdf，看起来不错，但如果知道问题的根源就更好了。

Answer 1

\maketitle是从通常\maketitle由加载的类给出的重新定义的article，最后\@maketitle由重新定义的宏courseoutline.cls——\@maketitle需要使用各种命令来设置大量信息。

这里编译失败是因为\@taemail和\@taphone尚未定义，同样，标准类也会失败，因为\title尚未使用。
