LuaLaTeX AMS-排版 sqrt 下 sum\limits 存在错误

LuaLaTeX AMS-排版 sqrt 下 sum\limits 存在错误

看起来 math-typeseeting 在lualatex使用时有一个错误ams。一个最小示例显示这一点

\documentclass[12pt]{report}
\usepackage{amsmath}

\begin{document}

This looks OK, but uses the "wrong" non-AMS-environment eqnarray

\begin{eqnarray}
  \label{eq:1}
  s&=\sqrt{\frac{1}{N-1}\sum\limits_{i=1}^N x_i}
\end{eqnarray}

This is no not OK and using the equation-environment
\begin{equation}
  \label{eq:1}
  s=\sqrt{\frac{1}{N-1}\sum\limits_{i=1}^N x_i}
\end{equation}

And again with align
\begin{align}
  \label{eq:1}
  s&=\sqrt{\frac{1}{N-1}\sum\limits_{i=1}^N x_i}
\end{align}

\end{document}

%%% Local Variables: 
%%% mode: latex
%%% TeX-engine: luatex
%%% coding: utf-8
%%% TeX-PDF-mode: t
%%% End:

最后 ( %%%%-preceded) 行是让 emacs 调用lualatex -shell-escape filename并生成 pdf 输出，在eqnarray-case 中是可以的（但很丑，不符合 AMS 风格），而在后两种情况下，会发生一些奇怪的事情：有一行是平方根，下面有一个大黑块，其余公式稍微低了一点。这完全搞砸了。

有人可以帮忙吗，我仍然希望这是我的错，而不是 TeX 的错（顺便说一句：它可以在“旧”latex -> dvi -> ps或pdf工作流程中正常运行。

答案1

用来LuaTeX​

\documentclass[12pt]{report}
    
\usepackage{amsmath}

\usepackage{unicode-math}
    
[...]

答案2

这就是我最终成功的方法：

感谢 Herbert，序言需要看起来像

\documentclass[12pt]{report}

\usepackage{amsmath}

\usepackage{unicode-math}
 
[...]

并更新了整个包

然而，在 Miktex 中，这需要从以下位置下载拉丁现代数学字体http://www.gust.org.pl/projects/e-foundry/lm-math/index_html 下载文件，将其放在....Miktex 2.9/fonts/opentype/public/lm 下，将其重命名为 lmmath-regular.otf 安装字体（Windows：双击 am 文件并点击“安装”）

或者，也可以使用 Miktex 字体，并将序言修改为

\documentclass[12pt]{report}%
\usepackage{amsmath}%
\usepackage{unicode-math}%
%\usepackage{fontspec}%
%\setmathfont{Asana Math}%
%\setmathfont{Xits Math}%
%\setmathfont{Cambria Math}%
[...]

其中 \setmathfonts... 必须通过删除前面的 % 来激活。

谢谢您的帮助
