类 moderncv 错误：未定义控制序列 \gitlabsocialsymbol

Question

您没有告诉我们您使用的是哪个modencv版本fontawesome。

最后，ubuntu（和 debian）安装了过时的 TeX Live 版本。最好使用原始的 TeX Live，您可以按照以下步骤安装这个问题。

如果您只想尝试fontawesome在 Ubuntu 上安装，请使用以下命令：

sudo apt-get install texlive-fonts-extra

确保 FNDB 已更新并且所有字体映射都已加载（我不使用 ubuntu，我不知道该操作系统如何做到这一点）。

安装 TeX Live new 后，您将丢失手动更新的moderncv。因此，最好将所需的更改添加moderncv到简历的序言中。

请参阅以下代码（我用标记了所有重要的代码更改<=========；请注意，我http在链接中将其更改为今天使用的、更安全的https）：

及其结果：

这是用当前类moderncv2.0.0（来自 ctan，而不是来自 github！）、当前 fontawesomefontawesome.sty 2016/05/15 v4.6.3.1 font awesome icons和当前 MiKTeX编译的pdfTeX, Version 3.14159265-2.6-1.40.20 (MiKTeX 2.9.6960 64-bit)。
