当 usepackage ifthen、changepage、ifoddpage 时，\@fileswith@pti@ns 的参数有一个额外的}

Question

当我使用\usepackage{ifthen}or/and \usepackage{changepage}or/and时\usepackage{ifoddpage}。

错误信息：

&#8203;! Argument of \@fileswith@pti@ns has an extra }.<inserted text>\par \usepackage{

! Paragraph ended before \@fileswith@pti@ns was complete.<to be read again>\par \usepackage{

最小代码：

\documentclass[a5paper,oneside,10pt]{article}
\usepackage[landscape,left=0.5cm,right=0.5cm,top=0.5cm,bottom=0.5cm]
\usepackage{ifthen}
\usepackage{changepage}
\usepackage{ifoddpage}
\begin{document}
abc
\end{document}
