每次我尝试使用标签和引用进行编译时都会引用未定义

我遇到了一个相当尴尬的问题。我决定开始使用 /label 和 /reference 来更好地组织我的笔记，但每当我使用 /ref 时，它都会给我一个未定义的错误，如下所示：

答案1

\label{a}无论如何，在环境中使用gather*都是没用的。

标签将被定义（并且不可能知道为什么你没有获得它），但\ref{a}会指向某个随机值，很可能是最后一个部分（无论它是哪个级别）的编号。在下面的示例代码中，它指的是 2，因为有第二个部分。

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\section{Test one}

Text

\section{Test two}

\begin{gather*}
1=Potato \label{a}
\end{gather*}

\ref{a}

\end{document}

在此处输入图片描述

当然，如果你使用，则引用方程编号gather，但是gather*，不是设定一个数字。

答案2

我能够通过某个我根本找不到的 tex stackexchange 帖子解决这个问题（我尝试了一个小时但无法再找到它），无论如何，该特定帖子的解决方案是将我的 latex-workshop 配方更改为以下内容：

"latex-workshop.latex.recipes": [
    {
        "name": "luatex -> biber -> luatex*2",
        "tools": [
            "luatex",
            "biber",
            "luatex",
            "luatex"
        ]
    },      
],
"latex-workshop.latex.tools": [{
    {,
        "name": "pdflatex",
        "command": "pdflatex",
        "args": [
            "-synctex=1",
            "-interaction=nonstopmode",
            "-file-line-error",
            "%DOC%"
        ]
    },
    {
        "name": "bibtex",
        "command": "bibtex",
        "args": [
            "%DOCFILE%"
        ]
    },
    {

        "args": [
