Rendering problem cross-reference equation in r markdown HTML

I usually reference equations in rmd using \label{} and \eqref{} combination. (I know \@ref, but this seems only works in bookdown::pdf_document or bookdown::html_document) For example,

---
title: "Untitled"
author: "Blended"
date: '2019 3 14 '
output:
  html_document: default
  pdf_document: default
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(comment = "#>")
```

\begin{equation} \label{eq:test}
  Y_i = \beta_0 + \beta_1 x_i + \epsilon_i
\end{equation}

Equation $\eqref{eq:test}$ works in PDF, but does not works in HTML.

This works well in pdf document.

However, when rendering html, it gives (???), not (1):

I think this is related to this issue: Support LaTeX environments in Markdown -> HTML conversion, i.e. MathJax occurs the error.

But I cannot see any solution of this.

Is it possible to use \eqref{eq:} normally in html document?

Add the following script at the beginning of your document body:

<script type="text/x-mathjax-config">
MathJax.Hub.Config({
  TeX: { equationNumbers: { autoNumber: "AMS" } }
});
</script>

It configures MathJax to automatically number equations. More details here.
