我在尝试使用系统字体时遇到问题
我猜测这是一个环境问题，但我就是不知道是什么原因造成的。
我有这个简单的 tex 文件：
\documentclass[10pt, a4paper]{article}
\usepackage{fontspec}
\setmainfont{Corporate S Regular}
\begin{document}
Test
\end{document}
字体“Corporate S Regular”作为系统字体安装：
>fc-list | grep "Corporate S Regular"
/usr/share/fonts/opentype/Corporate S Regular.otf: Corporate S:style=Regular
如果我以 root 身份在我的简单 tex 文件上使用 xelatex，一切都会按预期工作：

我得到了我的 PDF

生成失败，这使我相信如前所述这是一个配置问题，但我根本不知道从哪里开始寻找。

我发现了我的问题
这是一个愚蠢的权限错误，字体已安装，但文件权限仅允许 root 具有读取权限。
