编号自定义定理样式的问题

编号自定义定理样式的问题

我会尝试在 beamer documnet 中使用我的自定义样式，如果我使用非编号定义或另一个我的自定义样式来定义定理和例子

\begin{myDefinition*}{Sample Definition}
This is a sample definition.
\end{myDefinition*}

\begin{myExample*}{Sample Definition}
This is a sample definition.
\end{myExample*}

\begin{myQuestion*}{Sample Definition}
This is a sample definition.
\end{myQuestion*}

\begin{myTheorem*}{Sample Definition}
This is a sample definition.
\end{myTheorem*}

一切正常，但如果我 del *，那么我想使用编号的自定义环境，我会出现这样的错误：

Missing \endcsname inserted.

我认为，此错误与使用不同的语言包有关（当我重新定义 myDefinition 样式时）

并且定义的第一个符号（标题后的描述字段）未显示...我不明白，如何解决这个问题？

您的语法错误。您的自定义定理需要两个强制参数，一个用于标题，一个用于标签。您不能只省略一个。至少，它可以为空，但不能简单地缺失。
