beamer + minted 最基本的例子失败（不是“脆弱”的问题）

Question

我无法让最简单的 beamer+minted 示例运行。这是我的 latex 代码

\documentclass{beamer}
\usepackage{minted}
\begin{document}
\begin{frame}[fragile]
\begin{minted}{python}
class X(object):
    pass
\end{minted}
\end{frame}
\end{document}

我正在像这样运行 pdflatex

pdflatex -shell-escape main

并不断收到以下错误

! Argument of \@gobble has an extra }.
<inserted text> 
                \par 
l.14 \end{document}

Runaway argument?
! Paragraph ended before \@gobble was complete.
<to be read again> 
                   \par 
l.14 \end{document}

! Argument of \@firstofone has an extra }.
<inserted text> 
                \par 
l.14 \end{document}

Runaway argument?
! Paragraph ended before \@firstofone was complete.
<to be read again> 
                   \par 
l.14 \end{document}

! Undefined control sequence.

                                           =\ifbeamer@anotherslide 
l.14 \end{document}

! Incomplete \iffalse; all text was ignored after line 14.

                \fi

! Forbidden control sequence found while scanning text of \write.
<inserted text> 
                }

如果我只是忽略这些错误（例如，通过传递 -interaction=nonstopmode），我确实会得到一个大部分看起来不错的 pdf 文档；问题是最后有一个额外的页面，其中包含单词“document”。

有什么想法可能出错了吗？我在两个不同的 Linux 系统上尝试了这个示例，但两次都出现了相同的错误。

谢谢。
