为什么当我尝试使用 \autoref 获取方程的引用时只得到“??”

Question

我用\autoref它来引用论文中的所有内容。我可以毫无问题地获得图像和表格的引用，但当我尝试获取方程的引用时，我得到的只是??。

\noindent
Die Standardform eines Optimierungsproblems ist in \autoref{eq:generalOptimization} dargestellt.\\

\begin{align}
f(x)&   \longrightarrow  min/max  & x& =(x_1,x_2,\dots,x_n ) \nonumber  \\
wobei,          \qquad   g_i(x)& \leq 0                      & i& =(1,\dots,m) \label{eq:generalOptimization}\\
                         h_j(x)& = 0                         & j& = (1,\dotsb,p) \nonumber  
\end{align}\\

您有什么想法可以解决这个问题吗？也许是我正在使用的软件包存在问题：

Answer 1

您也\usepackage{mathtools}需要（改进公式内的非数学排版）。\begin{align}...\end{align}\text{}

但主要问题是\usepackage{hyperref}要\autoref工作。编译两次，看看效果。

编辑：这个解决方案的第一个版本是在 OP 添加他的“MWE”之前发布的，但现在很明显，包含cleveref包的错误位置是导致问题的原因（Mico 已经对此发表了评论）

cleveref是必须包含包的罕见情况之一后 \usepackage{hyperref}以使交叉引用正确。

\documentclass[12pt]{article}
\usepackage[ngerman]{babel}
\usepackage{mathtools}
\usepackage{hyperref}
\usepackage{cleveref}
