我正在尝试使用article类来键入一份简单的文档。
\documentclass[12pt, english]{article}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage{accents}
\DeclareMathAccent{\wtilde}{\mathord}{largesymbols}{"65}
\begin{document}
\pagestyle{empty}
\begin{figure}[ht]
\centering
\includegraphics[width=0.50\textwidth]{cm2.pdf}
\label{fig:cm2}
\end{figure}
\end{document}
编译时，我收到一条错误消息
Package graphics error:No driver specified
我该如何修复这个问题？这是生成的日志文件
