安装流程

1. 电脑安装最新版pandoc

2. 更新插件：

   npm uninstall hexo-renderer-marked --save
   npm uninstall hexo-math --save
   npm install hexo-renderer-pandoc --save
   npm install hexo-renderer-mathjax --save

3. 修改配置文件，修改theme/_config.yml中mathjax的设置，如下：

# Math Formulas Render Support

  # Default (true) will load mathjax / katex script on demand.
  # That is it only render those page which has `mathjax: true` in Front-matter.
  # If you set it to false, it will load mathjax / katex srcipt EVERY PAGE.
  per_page: true
 
  # hexo-renderer-pandoc (or hexo-renderer-kramed) required for full MathJax support.
  mathjax:
    enable: true
    # See: https://mhchem.github.io/MathJax-mhchem/
    mhchem: false
 
  # hexo-renderer-markdown-it-plus (or hexo-renderer-markdown-it with markdown-it-katex plugin) required for full Katex support.
  katex:
    enable: false
    # See: https://github.com/KaTeX/KaTeX/tree/master/contrib/copy-tex
