我正在尝试使用以下代码来制作titlePM格式的标题页。但以下代码不起作用。我该如何摆脱这个问题？
\documentclass{book}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{url}
\usepackage[svgnames]{xcolor}
\usepackage{pdfcolmk}
%% check if using xelatex rather than pdflatex
%%\usepackage{hyperref}
%% drawing package
\usepackage{tikz}
%% for dingbats
\usepackage{pifont}
\providecommand{\HUGE}{\Huge}% if not using memoir
\newlength{\drop}% for my convenience
%% specify the Webomints family
\newcommand*{\wb}[1]{\fontsize{#1}{#2}\usefont{U}{webo}{xl}{n}}
%% select a (FontSite) font by its font family ID
\newcommand*{\FSfont}[1]{\fontencoding{T1}\fontfamily{#1}\selectfont}
%% if you don’t have the FontSite fonts either \renewcommand*{\FSfont}[1]{}
%% or use your own choice of family.
%% select a (TeX Font) font by its font family ID
\newcommand*{\TXfont}[1]{\fontencoding{T1}\fontfamily{#1}\selectfont}
%% Generic publisher’s logo
\newcommand*{\plogo}{\fbox{$\mathcal{PL}$}}
%% Some shades

答案1
有两个主要错误。你有
\newcommand*{\wb}[1]{\fontsize{#1}{#2}\usefont{U}{webo}{xl}{n}}
而且应该是
\newcommand*{\wb}[2]{\fontsize{#1}{#2}\usefont{U}{webo}{xl}{n}}
（该命令有两个参数）。还有这个拼写错误：
\defincolor{Medium}{gray}{0.6}
应该缺少一个“e”：
\definecolor{Medium}{gray}{0.6}
（还有一些其他的\defincolor拼写错误，但它们已被注释掉；请确保你纠正它们；否则，当你取消注释它们时，它们会引发错误）。
修复上述问题后的结果（使用 xelatex）：
