! 字体 \TU/lmr/m/n/12=[lmroman12-regular]:+tlig; 12pt 无法加载：未找到度量数据或数据错误

Question

我目前正在使用 MikTeX 2.9.6809 和 LuaTeX 1.07.0，但我无法在 LuaLaTeX 中编译（但我可以在 XeLaTeX 和 pdfTex 中编译）。

遇到此错误后，我完全更新了 MikTeX，但问题仍然没有解决。甚至最基本的 Hello World 也无法编译。

\documentclass[a4paper,12pt]{report}

\begin{document}
Hello World
\end{document}

我遗漏了什么可能会导致此错误？

使用 12pt ：

(D:/Users/xxx.xxx/Documents/Software/MikTeX/texmfs/install/tex/latex/base
/size12.clo
! Font \TU/lmr/m/n/12=[lmroman12-regular]:+tlig; at 12pt not loadable: metric d
ata not found or bad.
<to be read again> 
relax 
l.54 \normalsize

使用 11 pt：

(D:/Users/xxx.xxx/Documents/Software/MikTeX/texmfs/install/tex/latex/base
/size11.clo
! Font \TU/lmr/m/n/10.95=[lmroman10-regular]:+tlig; at 10.95pt not loadable: me
tric data not found or bad.
<to be read again> 
relax 
l.54 \normalsize

使用 10pt（未在文档类中指定字体大小）

(D:/Users/xxx.xxx/Documents/Software/MikTeX/texmfs/install/tex/latex/base
/size10.clo
! Font \TU/lmr/m/n/10=[lmroman10-regular]:+tlig; at 10pt not loadable: metric d
ata not found or bad.
<to be read again> 
relax 
l.54 \normalsize

提前致谢

编辑：我发现的唯一相关问题! 字体 \TU/lmr/m/n/10=[lmroman10-regular]:+tlig; 10pt 处无法加载不会有帮助，因为它使用的是 TeX Live

Answer 1

对我来说，解决方法是运行：

luaotfload-tool --update --force

正如这里建议的：https://github.com/gregorio-project/gregorio/issues/1458#issuecomment-499215969

使用当前版本的 MiKTeX，我可以进行编译而不会出现错误或警告，请参阅文件.log：

前段时间 MiKTeX、LuaLaTeX 出现了问题，luaotfload有luaotfloadbug。现在的版本没有这个 bug...
