Latex 一行中有多个子图形。乳胶只能连续放置2个。子贷款错误

我正在尝试对齐一行中的几个子图形。两个数字很好。尝试包含第三个子图时，出现以下错误消息：文件在扫描@subfloat时结束\包括{doc}

此tex文档包含在主文件中，包括以下文件包：

\usepackage{graphicx}
\usepackage{subfigure}
\usepackage{subcaption}


%%%%%%new doc
\begin{figure}[h!]
\centering
\subfigure[a]{\includegraphics[width=0.1\textwidth]{Logos/Symbol_One_flow_path}}
\subfigure[b]{\includegraphics[width=0.1\textwidth]{Logos/1920px-Symbol_Two_flow_paths}}
\subfigure[c]{\includegraphics[width=0.1\textwidth]{Logos/Symbol_Two_flow_paths_(diagonally)} \subfigure[d]{\includegraphics[width=0.3\textwidth{Logos/Symbol_Two_flow_paths_with_connection}   
\subfigure[e]{\includegraphics[width=0.3\textwidth]{Logos/graph}    
\end{figure}

此问题可能是由于图c、d和e末尾缺少

}

。 这可以解释为什么你只有a和b两个数字

\usepackage{graphicx}
\usepackage{subfigure}
\usepackage{subcaption}

\begin{figure}[h!]
\centering
\subfigure[a]{\includegraphics[width=0.1\textwidth]{Logos/Symbol_One_flow_path}}
\subfigure[b]{\includegraphics[width=0.1\textwidth]{Logos/1920px-Symbol_Two_flow_paths}}
\subfigure[c]{\includegraphics[width=0.1\textwidth]{Logos/Symbol_Two_flow_paths_(diagonally)}} %one } was missing here !
\subfigure[d]{\includegraphics[width=0.3\textwidth{Logos/Symbol_Two_flow_paths_with_connection}} % here also
\subfigure[e]{\includegraphics[width=0.3\textwidth]{Logos/graph}} %and here 
\end{figure}

请制作一个可编译的包。为什么要混合使用子图形和子选项包？
