LaTeX 错误：命令‘\circledS’已定义。mathdesign 与 amssymb 冲突

tag-icon • tag-icon mathdesign amssymb
LaTeX 错误：命令‘\circledS’已定义。mathdesign 与 amssymb 冲突

此 MWE

\documentclass{article}
\usepackage[bitstream-charter]{mathdesign}
\usepackage{amssymb} 
\begin{document}
t
\end{document}

给出错误

! LaTeX Error: Command `\circledS' already defined.
See the LaTeX manual or LaTeX Companion for explanation.
l.160 ...mbol{\circledS}     {\mathord}{AMSa}{"73}

我改为{mathdesign}，现在我在所有使用包的文件中都收到此错误amssymb

有什么技巧可以让这两个包在同一个文件中工作吗？

如果您更喜欢\circledS，那么amssymb以下内容就足够了：

\documentclass{article}
\usepackage[bitstream-charter]{mathdesign}
\let\circledS\undefined % here - PS
\usepackage{amssymb} 
\begin{document}
t
\end{document}
