我一直在 texlive 2017 中使用 stix 字体。现在我收到了奇怪的错误消息。这是一个最低限度的工作示例：
\documentclass{book}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{amsthm}
\usepackage{stix}
\begin{document}
\(\cos^2\theta+\sin^2\theta=1\)
\end{document}
由于日志太长，我正在重现一个编辑过的版本。

我在开始文档时收到以下错误消息。！LaTeX 错误：此 NFSS 系统未正确设置。`` 是否是因为 texlive 2018 安装已损坏？
答案1
当。。。的时候stix包裹TeX Live 上更新，必要的字体描述.fd文件被删除了，我认为这是一个错误，因为甚至.fdd添加了一个新文件（.fd文件的单独来源）。
临时解决方案，直到情况得到解决：复制stix.fdd工作目录中的文件
cp /usr/local/texlive/2018/texmf-dist/source/fonts/stix/stix.fdd .
并tex在上面运行
tex stix.fdd
这将生成必要的.fd文件，并且 LaTeX 应该很乐意运行您的旧文档。
如果你的系统上没有stix.fdd，你可以直接从 CTAN 下载：http://mirrors.ctan.org/fonts/stix/latex/stix.fdd
用于stix2较新的。
