我有各种我通常用 Latex 编写的文档的类。我刚刚在新工作中迁移到 Mac，发现我的脚本都无法在 MacTex 2018 上使用（第一次使用 MacTex...）。
我得到的唯一错误是：
未定义控制序列。\end{document}
这意味着我的文件有问题.cls，但该错误使得无法调试它。
有趣的是，我的所有文件在 TexLive 2018 下的 Ubuntu 机器上都能完美运行。为什么它们不能在 Mac 上运行？
请看一下这封简单信件的 MWE。
这是我的.cls文件：

文件中是否有任何明显.cls无法与 MacTex 配合使用的内容？抱歉，它很长，但我真的不知道该如何调试它。非常感谢！
