看一下这个 XeLaTeX 文件：
\documentclass{memoir}
\usepackage{longtable}
\usepackage{hyperref}
\usepackage{bidi}
\begin{document}
\begin{longtable}{l}
x
\end{longtable}
\end{document}
当我尝试编译它时，出现以下错误：
! Undefined control sequence.
<argument> \@currentHref
l.10 \end{longtable}
如果我从包列表中删除其中一个hyperref或一个，一切都会正常。不幸的是，我需要这两个包。bidi
我能做些什么？
编辑：添加 \listfiles
该\listfiles命令给出以下列表：

答案1
似乎关键的区别在于，在当前的 texlivebidi中
Package: bidi 2015/02/17
您的版本比 旧了一年。您至少应该更新bidi，它显然已经修复了这个问题。
