取自组合包文档，fontspec在开头添加包，失败并出现错误：

有人能想到解决方法吗？这些软件包不兼容吗？
同样的，在旧版本中也可以编译。我最近更新了整个 latex 机制，现在它不起作用了（我花了一段时间才弄清楚一个最小的例子）。
要编译上面的例子，你需要一个虚假的art1.tex文件art2.tex，我使用了：
\documentclass[12pt,twocolumn,a4paper]{article}
\title{Organic photovoltaic cells for space applications}
\author{Pippo}
\begin{document}
\label{paper:myname}
\maketitle
\begin{abstract}
blah1
\end{abstract}
\section{Introduction}
blah2
\end{document}
