我正在尝试将编译链从 lualatex + dvips + ps2pdf 更改为 pdf 模式下的 lualatex。以前可以正常工作的某些功能现在不再起作用了。
例如，此代码：
%-*- coding: utf-8 -*-
\documentclass{article}
\usepackage[svgnames]{xcolor}
\begin{document}
\white Text
\end{document}
产生错误：
This is LuaTeX, Version 1.12.0 (MiKTeX 2.9.7300 64-bit)
restricted system commands enabled.

将白色改为白色也不起作用......
