定理环境未在 distill 中呈现或交叉引用
Theorem environment not rendering or cross-referencing in distill
我正在尝试写一篇 distill::distill_article 博文，它需要使用 LaTeX 数学环境，例如定理、引理、证明等
我已尝试遵循这些 instructions and also these instructions 但无法呈现 theorem 环境，无论是使用 LaTeX 块还是 rmarkdown 块。
我还注意到 被问及在 bookdown 中具体使用 distill::distill_article。此修复程序也不起作用。请注意，我的用例是在 distill::distill_article 内使用 bookdown 定理环境，而不是相反。
这是问题的代表：

# Main theorems
With the definitional background established, let's move onto the
main theorem of this article.
\begin{align}

We have a labeled and named theorem below, and \@ref(nthm:deltamethod).

::: {.theorem #pythagoras name="Pythagorean theorem"}
For a right triangle, if $c$ denotes the length of the hypotenuse
and $a$ and $b$ denote the lengths of the other two sides, we have
$$a^2 + b^2 = c^2$$
:::

请注意，我在 rmarkdown 中加载了 bookdown，目的是渲染定理环境。但是它不起作用，即不呈现定理或交叉引用。谁能帮忙解决这个问题？

我没有完成所有这些，但这是引理的一个。这使用了两个 classes：lemma 和 lemmaS。当您使用 class 引理时，它会更改整数，当您使用引理 S 时，它会增加小数点。此方法可应用于所有不同类型的公式块。

边看边打字，我想到了一些方法可以使它更干净...但我只是希望它能正常工作！我确信有一种方法可以只使用一个 class 引理，使用标题来表示何时递增整数。无论哪种方式，这都应该让您有其他选择。如果您不想要数字，请使用定理设置，只需将单词 theorem 更改为您想要查看的单词即可。如果你想给它们编号，把词引理改成你想出现的词。如果您想要以上所有内容，请在 CSS.
中附加名称
例如，要使用编号，但要添加推论 - 您可以在未使用“内容”一词的地方追加，在使用“内容”的地方复制并更改该词：
.corrolary,
.lemma,
.lemmaS,
.theorem { /* updated to add two types of lemma */
display: block;
font-style: italic;
}
.corollary::before{. /* Copy of .theorem, updated for Corollary */
content:"Corollary. ";
font-weight: bold;
font-style: normal;
}
bookdown 功能可以使用 base_format 参数与其他单一格式一起使用，如 here.
所述
如果 bookdown 的所有功能都不是 100% 兼容 distill 格式，则定理和证明处理应该是。所以这会起作用：

For a right triangle, if $c$ denotes the length of the hypotenuse
and $a$ and $b$ denote the lengths of the other two sides, we have

边看边打字，我想到了一些方法可以使它更干净...但我只是希望它能正常工作！我确信有一种方法可以只使用一个 class 引理，使用标题来表示何时递增整数。无论哪种方式，这都应该让您有其他选择。如果您不想要数字，请使用定理设置，只需将单词 theorem 更改为您想要查看的单词即可。如果你想给它们编号，把词引理改成你想出现的词。如果您想要以上所有内容，请在 CSS.
中附加名称例如，要使用编号，但要添加推论 - 您可以在未使用“内容”一词的地方追加，在使用“内容”的地方复制并更改该词：
.corrolary,
.lemma,
.lemmaS,
.theorem { /* updated to add two types of lemma */
display: block;
font-style: italic;
}
.corollary::before{. /* Copy of .theorem, updated for Corollary */
content:"Corollary. ";
font-weight: bold;
font-style: normal;
}
bookdown 功能可以使用 base_format 参数与其他单一格式一起使用，如 here.
如果 bookdown 的所有功能都不是 100% 兼容 distill 格式，则定理和证明处理应该是。所以这会起作用：
---
title: "Test Title"
description: |
Test description
author: Test author
date: 2021-12-31
output:
bookdown::html_document2:
self_contained: false
base_format: distill::distill_article
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
# TL;DR;
Trying to ensure that theorem environments are working in `distill::distill_article`.
::: {#pythagoras .theorem name="Pythagorean theorem"}
For a right triangle, if $c$ denotes the length of the hypotenuse and $a$ and $b$ denote the lengths of the other two sides, we have

:::
We have a labeled and named theorem below, and \@ref(thm:pythagoras).
您将获得与 bookdown 中相同的 HTML 渲染。
