moderncv我从去年年初就开始学习准备简历，但对细节还不太熟悉。
我在简历中添加了“裁判”部分，使用代码其他用户推荐。它以前运行得很好，但现在看来有些代码已经过时了，代码无法运行。每当我编译代码时，我都会收到以下消息：
! Undefined control sequence. <argument>
\listdoubleitemmaincolumnwidth
所以我猜测问题出在上述论点上，但我可能错了。
以下是一个例子：
\documentclass[11pt,a4paper,sans]{moderncv}
%% ModernCV themes
\moderncvstyle{casual}
\moderncvcolor{blue}
\renewcommand{\familydefault}{\sfdefault}
\nopagenumbers{}
%% Character encoding
\usepackage[utf8]{inputenc}
%% Adjust the page margins
\usepackage[scale=0.75]{geometry}
%% Personal data

\familyname{Doe}
\title{Resumé title (optional)}
\address{street and number}{postcode city}
\mobile{+1~(234)~567~890}

答案1
好吧，一个快速而肮脏的解决方案是定义缺失的变量（在今天的过时版本中使用moderncv）new并设置一个适当的值，例如
\newlength{\listdoubleitemmaincolumnwidth}%
\setlength{\listdoubleitemmaincolumnwidth}{6.5cm}%
（更改6.5cm为您需要的值...）
完成 MWE：
\documentclass[11pt,a4paper,sans]{moderncv} % version ??
%% ModernCV themes
\moderncvstyle{casual}
\moderncvcolor{blue}
\renewcommand{\familydefault}{\sfdefault}
\nopagenumbers{}
