moderncvstyle经典如何解决名称错误？

Question

请检查您使用的课程版本moderncv！当前版本是 2.0.0。

例如，手机（旧版）的命令\phone已随当前版本更改为

\phone[fixed]{\color{black}+32-xxx-xxx-xxx} % <====================

使用以下 MWE（参见标有的重要代码更改<=======）

%\listfiles %        to check used packages and version numbers

\moderncvstyle{classic} % head[left,right] 1; body 1; foot

你得到了（我认为）期望的结果：

因为不清楚您使用的版本，所以我只注释了手机和传真号码的显示。如果您想要自动解决方案，我们需要知道moderncv您使用的是哪个版本，或者只需更新到当前版本 2.0.0。

要检查您使用的软件包和版本，您可以将命令\listfiles作为代码的第一行添加，编译 3 次，然后检查日志文件。在那里，您将找到所用软件包和版本的列表。请复制它并将其添加到您的问题中。
