linuxmint 中的 latexdiff 正则表达式中未转义的左括号已被弃用，在正则表达式中传递；

Question

我使用的是 linuxmint 操作系统，是一个相对较新的 Linux 用户，我发现很多人在使用 latexdiff 时都遇到了这个问题，但我不知道如何解决这个问题，并且花了很多时间。在阅读了几篇文章后，我以为这个问题已经在新版 latexdiff 中得到了解决，但我不知道如何安装它，也找不到适合我系统的明确说明。我试过 sudo apt-get install latexdiff，但它说 latexdiff 已经是最新版本 (1.1.1-1)。

    $ latexdiff --v

Option v is ambiguous (verbose, version, visible-label)
2 and only 2 non-option arguments required.  Write latexdiff -h to get help
