如何将定理插入到 tcolorbox？

Question

我尝试插入一个tcolorbox没有标题的定理。

以下是 MWE (与 LyX 合作)：

现在，如果您删除包含该内容的行，则<=============================无法编译，您知道原因是什么吗？我该如何修复它？

（我尝试删除一些代码行但总是出现错误）

谢谢你！

::编辑:: 这里是其他 MWE：

\documentclass{scrartcl}

\usepackage{tcolorbox}
\newtheorem{theorem}{Theorem}

\begin{document}

%\tcbox{ <=============================
\begin{theorem}
Let $f$ be 
\end{theorem}
%} <=============================
\end{document}

Answer 1

当我使用\begin{tcolorbox}...\end{tcolorbox}它时，它对我有用。

\documentclass{scrartcl}
\usepackage{tcolorbox}
\newtheorem{theorem}{Theorem}
\begin{document}
\begin{tcolorbox} %<=============================
\begin{theorem}
Let $f$ be 
\end{theorem}
\end{tcolorbox} %<=============================
\end{document}

根据手动的与以下方法相比，这种方法似乎不太可能限制您\tcbox：
