请问我如何才能将 fancyhdr 包与 natbib 包一起使用。我碰巧无法在我的文档中使用这两个包，这是什么问题？我该如何纠正？

\chapter{Introduction}
Ordinary differential equations (ODEs) are commonly employed to represent the behavior of dynamic systems in various fields of science and engineering. However, ODEs have certain limitations when it comes to describing dynamics that involve discontinuities, impulses, and uncertain behaviors. Consequently, ordinary differential inclusions (ODIs) have been successfully employed as a useful approach to model such systems.\\
The concept of differential inclusion was studied broadly by Jean-Pierre Aubin, a mathematician from France, during the early 1980s. Differential inclusion is a versatile mathematical tool that extends the scope of differential equations and is utilized to represent diverse phenomena in both physical and social sciences. ODIs have applications in many fields, including control theory, economics, and population dynamics, physics, etc.\\[5pt]
In recent times, ODIs have gained considerable attention, and researchers have increasingly shown interest in exploring the characteristics of the solution set of ODIs, such as their properties of boundedness, uniqueness, and existence.\\[5pt]
The objective of this study is to examine and review the set of solutions for ordinary differential inclusions (ODIs) and establish criteria for the existence of solutions.\\[5pt]
Additionally, we apply our findings to a diverse range of examples in fields such as control theory, economics, and biology.

您认为不能同时使用fancyhdr和包的假设natbib肯定是错误的。许多文档都使用了这两个包，例如：
\begin{filecontents}[overwrite]{\jobname.bib}
@misc{pkg:fancyhdr,
author={Pieter van Ostrum},
title={{\textsc{fancyhdr}}---Extensive control of page headers and footers in {\LaTeXe}},
year=2022,
note={\url={https://ctan.org/pkg/fancyhdr}},
}
@misc{pkg:natbib,
author={Patrick W. Daly},
title={{\textsc{natbib}}---Flexible bibliography support},
year=1993,
note={\url{https://ctan.org/pkg/natbib}},
}
\end{filecontents}
\documentclass[twoside]{report}
\usepackage{natbib}
\usepackage{fancyhdr}
\usepackage{url}
\usepackage[nottoc]{tocbibind}% bibliography entry (an others) to the ToC
%\usepackage{parskip}% Try this, if you want paragraph distance instead of first line indent.
\usepackage{mwe}% Useful for dummy text in minimal working examples.
\fancyhead[RE]{\scshape\nouppercase \leftmark}% makes sense only with class option twoside
\fancyhead[LO]{\scshape\nouppercase \rightmark}
\fancyhead[RO,LE]{\thepage}% LE makes sense only with class option twoside
\fancyfoot[C]{}
\renewcommand{\headrulewidth}{0pt}
\renewcommand{\footrulewidth}{0pt}
\pagestyle{fancy}
\bibliographystyle{apalike}% simply an author-year-style but without any relation to APA

\chapter{Using packages \textsc{natbib} and \textsc{fancyhdr} together}
There isn't a real problem in using packages \textsc{natbib}
\citep{pkg:natbib} and \textsc{fancydr} \citep{pkg:fancyhdr} together. Indeed
these packages are independent and usually do not influence each other.

If there would be additional entries in the bibliography, so that it would
need more than one page, you would get the same page header on even
bibliography pages like on this page.
\clearpage
If there would be additional entries in the bibliography, so that it would
need more than two pages, you would get the same page header on odd
bibliography pages like on this page.

所以我猜你的问题不是这两个包的组合，而是另一个。但不幸的是，你的问题既没有告诉我们问题所在，也没有告诉我们预期的结果。因此，我几乎不指望这个答案能告诉你更多信息，除了你认为这两个包不兼容的基本假设是不正确的。
