在投影机覆盖层中铸造

Question

我意识到以前也曾有人问过类似的问题，但到目前为止还没有解决办法。

---

考虑这个文档：

\documentclass{beamer}

\usepackage{minted}

\begin{document}

\begin{frame}[fragile]
\only<2>{
\begin{minted}{agda}
test
\end{minted}
}
\end{frame}

\end{document}

它给出了以下错误：

! FancyVerb Error:
  Extraneous input ` test \end {minted} ' between \begin{minted}[<key=value>] a
nd line end
.
\FV@Error ... {FancyVerb Error:
\space \space #1
}

l.5 }

This input will be discarded. Hit <return> to continue.

)
Runaway argument?
! File ended while scanning use of \FancyVerbGetLine.
<inserted text> 
                \par 
l.13 \end{frame}

I suspect you have forgotten a `}', causing me
to read past where you wanted me to stop.
I'll try to recover; but if the error is serious,
you'd better type `E' or `X' now and fix your file.

! FancyVerb Error:
  Couldn't find `\end{minted}' to end a verbatim environment on input line 5.
.
\FV@Error ... {FancyVerb Error:
\space \space #1
}

l.13 \end{frame}

Probably you mistyped the environment name or included an extraneous 
space, or are using an improperly defined verbatim environment. 
Hit return and I will try to terminate this job.


[...]

Things are pretty mixed up, but I think the worst is over.

（最后一句很美，我需要把它加进去。）

怎么了？我该如何解决？请注意，它\mintinline运行正常。

使用的问题\only{...}在于，你不能拥有像宏参数这样脆弱的内容（例如https://tex.stackexchange.com/a/30006/36296了解更多解释）。

幸运的是，你可以使用onlyenv环境来代替：

\documentclass{beamer}

\usepackage{minted}

\begin{document}

\begin{frame}[fragile]
\begin{onlyenv}<2>
\begin{minted}{agda}
test
\end{minted}
\end{onlyenv}
\end{frame}

\end{document}
