我在 LyX 中的 tufte-book 类中编写并定义了一个自定义 tcolorbox（LyX 中的彩色框），如下所示：
现在，我在“颜色框选项”中输入文本label={truck}并引用，\ref={truck}引用结果为??。即使我从 LyX 参考文档中复制了彩色框的工作示例，也不起作用。插入
结果是
既然它在参考文档中起作用，那么它一定与自定义框 2 或文档类的定义有关？任何帮助解决此问题的帮助都将不胜感激。
编辑：以下是一个文档示例：

我在下面的文件中所做的是使用两个参数而不是一个参数来定义 tcolorbox，第一个参数用于可选定义标题，第二个参数用于标签。
我应该指出，TeX 会忽略命令名后的空格，这就是为什么 中没有空格\thetcbcounter #1，我假设你想要这里有一个空格，所以我把它改成了\thetcbcounter\ #1。

请注意，我删除了你的序言，因为演示不需要它，而且我想使代码更短。
如果你想在 LyX 中自定义你的定理，我可以推荐一个我为此目的编写的模块，可以在这里。使用此模块，您可以获得文件中当前的样式，但您可以像往常一样使用 LyX 的参考系统，并且定理布局将看起来相同（在 LyX 的 GUI 内部）与通常的定理模块提供的普通定理相同（因此您可以看到定义的编号）。
