答案1
LaTeX 仅加载一次包。如果对已加载的包执行进一步的\usepackage命令\RequirePackage，LaTeX 仅检查选项，如果发现任何在加载包时不存在的新选项，则发出警告。
例子：
\documentclass{article}
\usepackage{color}% might be hidden in a package
\usepackage[usenames,dvipsnames]{color}
\begin{document}
\end{document}
LaTeX 抱怨“选项冲突”错误消息。按“h”键可显示详细信息：
! LaTeX Error: Option clash for package color.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.4 \begin
{document}
? h
The package color has already been loaded with options:
[]
There has now been an attempt to load it with options
[usenames,dvipsnames]
Adding the global options:
,usenames,dvipsnames
to your \documentclass declaration may fix this.
Try typing <return> to proceed.
?
全局选项
帮助文本还提供了一种解决方法，将选项放入全局选项中。但是，考虑到选项名称（例如），其他软件包可能会看到它们，这可能不是最佳选择draft。因此，如果以下方法失败，我将使用全局选项作为最后的手段。
使用所有选项提前加载
如果包加载顺序无关紧要，则可以在较早的阶段使用所有选项加载包：
\documentclass{article}
\usepackage[usenames,dvipsnames]{color}
% ...
\usepackage{color}% might be hidden in a package
% ...
\usepackage[usenames,dvipsnames]{color}
% ...
\usepackage[dvipsnames]{color}
\PassOptionsToPackage
通常包加载不是显式的，而是隐藏在其他包甚至类中。然后\PassOptionsToPackage帮助也可以使用前 \documentclass：
\PassOptionsToPackage{usenames,dvipsnames}{color}
\documentclass{...}
...
