类 moderncv：renewcommand makecvtitle 导致未定义的控制序列错误

这个问题与另一个问题相关这里几年前。当时的目标是在使用 制作的经典简历中，将联系方式设置在姓名下方moderncv。

我只是尝试复制代码：

\documentclass[11pt,a4paper,sans]{moderncv}
\moderncvstyle{classic}
\moderncvcolor{blue}

\makeatletter
\renewcommand*{\makecvtitle}{%
  % recompute lengths (in case we are switching from letter to resume, or vice versa)
  \recomputecvlengths%
  % optional detailed information box
  \newbox{\makecvtitledetailsbox}%
  \savebox{\makecvtitledetailsbox}{%
    \addressfont\color{color2}%
    \begin{tabular}[b]{@{}p{10cm}@{}}%
      \ifthenelse{\isundefined{\@addressstreet}}{}{\makenewline\addresssymbol\@addressstreet %
        \ifthenelse{\equal{\@addresscity}{}}{}{\makenewline\@addresscity}} % if \addresstreet is defined, \addresscity will always be defined but could be empty
      \ifthenelse{\isundefined{\@mobile}}{}{\makenewline\mobilesymbol\@mobile} %
      \ifthenelse{\isundefined{\@email}}{}{\makenewline\emailsymbol\emaillink{\@email}}%

        \setlength{\fboxsep}{0pt}\fi%

但是，我收到了几个以 开头的错误!Undefined control sequenec error。一旦我注释掉 renewcommand 函数，错误就消失了。

以下是文件中的一段代码，log但它对我没有太大帮助：

! 未定义的控制序列。\makecvtitlenamewidth =0pt l.66 \makecvtitle 错误消息顶行末尾的控制序列从未被 \def 过。如果您拼错了它（例如， \hobx'), typeI'）和正确的拼写（例如，`I\hbox'）。否则继续，我会忘记未定义的内容。

! 缺少数字，视为零。= l.66 \makecvtitle 这里应该有一个数字；我0'. (If you can't figure out why I needed to see a number, look up在 The TeXbook 索引中插入了“奇怪的错误”。)

! 非法测量单位（插入 pt）。= l.66 \makecvtitle 尺寸的单位可以是 em、ex、in、pt、pc、cm、mm、dd、cc、nd、nc、bp 或 sp；但您的单位是新的！我假设您指的是 pt，表示打印点。要从此错误中顺利恢复，最好删除错误的单位；例如，键入“2”以删除两个字母。（请参阅 TeXbook 的第 27 章。）

! 未定义的控制序列。\makecvtitlenamewidth l.66 \makecvtitle 错误消息顶行末尾的控制序列从未被 \def 过。如果您拼错了它（例如， \hobx'), typeI'）和正确的拼写（例如，`I\hbox'）。否则请继续，我会忘记未定义的内容。

! 缺少数字，视为零。\let l.66 \makecvtitle 这里应该有一个数字；我0'. (If you can't figure out why I needed to see a number, look up在 The TeXbook 索引中插入了“奇怪的错误”。)

! 非法计量单位（插入 pt）。 \let l.66 \makecvtitle

您能帮我使该示例可编译吗？

答案1

在早期版本中，使用的变量在当前版本（版本 2.0.0）中\makecvtitlenamewidth已被重命名为。\makecvheadnamewidthmoderncv

因此，您必须在代码中更改变量名称。请参阅以下 MWE（更改标有<==============）：

\documentclass[11pt,a4paper,sans]{moderncv}
\moderncvstyle{classic}
\moderncvcolor{blue}

% Variable \makecvtitlenamewidth is renamed to \makecvheadnamewidth
\makeatletter
\renewcommand*{\makecvtitle}{%
  % recompute lengths (in case we are switching from letter to resume, or vice versa)
  \recomputecvlengths%
  % optional detailed information box
  \newbox{\makecvtitledetailsbox}%
  \savebox{\makecvtitledetailsbox}{%
    \addressfont\color{color2}%
    \begin{tabular}[b]{@{}p{10cm}@{}}%
      \ifthenelse{\isundefined{\@addressstreet}}{}{\makenewline\addresssymbol\@addressstreet %
        \ifthenelse{\equal{\@addresscity}{}}{}{\makenewline\@addresscity}} % if \addresstreet is defined, \addresscity will always be defined but could be empty
      \ifthenelse{\isundefined{\@mobile}}{}{\makenewline\mobilesymbol\@mobile} %
