我从 texlive 2016 移至 texlive 2020。类似这样的事情：
\includegraphics[quiet,scale=0.5]{OIP}
之前可以正常工作，但出现错误：
Package keyval Error: No value specified for quiet。
我正在使用 catalina 下的 iMac 并使用最新版本的 macTeX 软件包。
我用来测试的代码是
\documentclass[12pt]{article}
\usepackage{graphicx} \begin{document}
\includegraphics[quiet,scale=0.5]{OIP}
\end{document}
其中“OIP”是您想要的 pdf 中的任何图像。我得到的完整日志如下：

我不知道是什么导致了这种行为的改变，但以下内容提供了一个临时的解决方案：
\documentclass[12pt]{article}
\usepackage[]{graphicx}
\makeatletter
\providecommand\KV@Gin@quiet@default{\KV@Gin@quiet{}}
\makeatother
\begin{document}
\includegraphics[quiet,scale=.5]{example-image-duck}
\end{document}
