请考虑以下文档：
\documentclass{article}
\usepackage{unicode-math}
\usepackage{hyperref}
\begin{document}
aaa
\end{document}
当我用它编译它时lualatex，出现以下错误：
! Undefined control sequence.
<argument> \Url@FormatString
l.5037 \let
\HyOrg@url\url
?
如果我把放在hyperref前面unicode-math，我会得到一个不同的错误：
! Undefined control sequence.
<argument> \Url@FormatString
l.2317 }
奇怪的是，第一个文档（确切地说是更复杂的文档，我简化为这个示例的文档）昨天才对我有用。我没有更新系统的任何部分；我尝试恢复到以前的提交，但这也没有帮助。有人知道是什么原因导致这个问题吗？
系统详细信息：
- OSX 10.8.5
- 2013年纺织现场展
- luatex r30581、hyperref r28213、unicode-math r30504

我说“我没有更新系统的任何部分”并不完全正确。我已经latex2html通过homebrew，出乎意料的是，将几个样式文件安装到用户本地 TeX 主目录中。这些文件中有一个旧版本，url.sty它似乎与几乎所有内容都冲突。删除此样式文件可修复此问题。
