Overleaf 给我一个错误，说 if-else 不完整。文档中没有任何 if-else。我不确定为什么会出现错误。
如果我注释掉第二个，\item编译器就可以渲染 pdf。所以我想知道：
- 如何将多个条目添加为项目符号？
- 什么确切地
if-else错误是什么？正如我所说，文档中没有。

这是resume.cls文件：

这是编译器的错误消息。
Incomplete \iffalse; all text was ignored after line 19.
inserted text>
\fi
<*> ExtraResumeFields.tex
The file ended while I was skipping conditional text.
This kind of error happens when you say `\if...' and forget
the matching `\fi'. I've inserted a `\fi'; this might work.
! Emergency stop.

答案1
事实上，您的文档中确实有 if-else 语句，只是不太明显，因为它们隐藏在 的定义中frcontent。我认为问题基本上在于您使用的是frcontent只有 2 个参数的宏，而它实际上被定义为具有 4 个强制参数的环境。正如 lukeflo 在评论中指出的那样， 也是如此csection：它被定义为具有 2 个参数的环境，因此应该这样使用。
下面编译没有错误。
