\tcbtheorem 中的失控论点

Question

以下 MWE

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[many]{tcolorbox}

\newtcbtheorem{defbox}{Definition}%
{   enhanced,
    arc=0mm,
    interior style={white},
    attach boxed title to top center= {yshift=-\tcboxedtitleheight/2},
    fonttitle=\bfseries,
    fontupper=\itshape,
    colbacktitle=white,coltitle=black,
    boxed title style={size=normal,colframe=white,boxrule=0pt}
}

\begin{document}

\begin{defbox}{Theorem Name}
Description
\end{defbox}

\end{document}

产生以下（裁剪的）输出

但我的编辑也说，这里有一个失控的论证。可能出于同样的原因，在 tcbtheorem 之前有一个不合适的 D。

我的错误日志（我想？）说

 main.tex, line 19
Runaway argument?

{
! Paragraph ended before \tcb@theo@label was complete.
<to be read again> 
                   \par 
l.19 D
      escription
I suspect you've forgotten a `}', causing me to apply this
control sequence to too much text. How can we recover?
My plan is to forget the whole thing and hope for the best.

! Extra }, or forgotten \endgroup.
<argument> \tcb@theo@label {\par }
                                  {D}
l.19 D
      escription
I've deleted a group-closing symbol because it seems to be
spurious, as in `$x}$'. But perhaps the } is legitimate and
you forgot something else, as in `\hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the
deleted material, e.g., by typing `I$}'.

尽管我部分理解什么是失控论点，但我在这里没有找到它，而且我不知道下一步该怎么做。

任何帮助，将不胜感激。

Answer 1

你错过<prefix>了\newtcbtheorem（参见第 340 页）手动的) 和<label>的论点\begin{defbox}。

利用<prefix>和，<label>您可以引用您的定理\ref{<prefix>:<label>}：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[many]{tcolorbox}

\newtcbtheorem{defbox}{Definition}%
{   enhanced,
    arc=0mm,
    interior style={white},
    attach boxed title to top center= {yshift=-\tcboxedtitleheight/2},
    fonttitle=\bfseries,
    fontupper=\itshape,
    colbacktitle=white,coltitle=black,
    boxed title style={size=normal,colframe=white,boxrule=0pt}
}{th}

\begin{document}

\begin{defbox}{Theorem Name}{mytheorem}
Description of theorem~\ref{th:mytheorem}.
\end{defbox}

\end{document}
