我更新了所有 miktex 包，现在无法运行unicode-math。我收到一条消息，但似乎无法调试它。我收到错误：
("E:\software\MiKTeX 2.9\tex\latex\filehook\filehook.sty")
! Undefined control sequence.
<argument> \LaTeX3 error:
The deprecated command '\luatex_if_engine:T' has ...
l.408 \luatex_if_engine:T
{ \RequirePackage{unicode-math-luatex} \endinput }
?
Process has been terminated ...
这是一个出现错误的简单 tex 文件：
\documentclass[11pt]{article}
%%% lipsum
\usepackage{lipsum}
%%% FONTS %%%
\usepackage{unicode-math}
\begin{document}
\lipsum
\end{document}
出现错误的代码实际上位于文件的第 408 行unicode-math.sty：
\luatex_if_engine:T { \RequirePackage{unicode-math-luatex} \endinput }
\xetex_if_engine:T { \RequirePackage{unicode-math-xetex} \endinput }
有人知道这是什么问题吗？
谢谢

这是漫游配置文件中先前安装的本地包与 miktex 应查找的全局包之间的冲突。删除漫游包可解决问题。
