博客内容带有latex数学公式时，启动失败

[acptek]

I want to create a new issue

• Yes, I have read FAQ.
• Yes, I have read Hexo Docs page.
• Yes, I have read Hexo-theme-stun Docs.
• And yes, I already searched for current issues and this did not help me.

Stun Information

Stun Version:
Stun Version: 1.4.1

Platform:
Windows

Browser:
Chrome

Expected behaviour

Start the Blog by excuting the command "hexo s", and then it renders the latex successfully.

Actual behaviour

The Blog startup failed.

(对于之前发布带有latex公式的博客，即使能在写完内容后本地启动博客，但是却无法渲染数学公式，本该显示公式的地方变为了空白)

Steps to reproduce the behaviour

1. configure the mathjax according to the DOC
2. set "math: true" in Front-matter
3. write and save the blog
4. excute command "hexo s"

I found the mistake related in thewebsite:

你好，麻烦提供下你的 Hexo 根目录下的 package.json 中的内容和你的文章 Markdown 源文件中有关 LaTex 公式那块的截图。还有，请问数学公式的渲染引擎你选择的是 MathJax 还是 KaTex?

package.json :

{
  "name": "hexo-site",
  "version": "0.0.0",
  "private": true,
  "hexo": {
    "version": "3.9.0"
  },

Latex :

$$
\begin{align}\textbf{特殊正交群}:\\&SO(n)=\{R\in\R^{n\times n}|RR^T=I,det(R)=1\}.\end{align}
$$
其中，I为单位矩阵

关于${a}'=R^{-1}a=R^Ta$ ，同样地，正交矩阵R的逆矩阵在几何上表示一个相反的旋转，因此R的转置刻画了一个相反的旋转。



#### 旋转 + 平移

刚体运动（由向量a变换到向量a'），旋转Ra和平移向量t
$$
\textbf{a'=Ra+t}
$$

选择的是 mathjax

[acptek]

非常感谢，关于不能启动的问题我已解决：
在书写latex时，将 "{{"写成 "{ {"可以避免报错

但是关于页面公式无法显示的问题依然存在

[liuyib]

问题已解决，commit 记录：fix(#16): Solved that mathjax is not working properly。
我这边测试没问题了，效果如下：

你更新下主题应该就可以正常使用了。如果还有问题，可以再接着提问；如果没问题了，就把 Issue 关闭吧 😄。
