我试图通过配置 _config.yml 使 Octopress 使用默认降价解析器 Rdiscount (2.1.7) 生成 TOC，但它没有工作并且rake generate失败了。
我用 Sinatra 在 RDiscount :generate_toc中尝试了答案，但它对我也不起作用。
所以我想知道是否有办法像这样配置 Octopress Rdiscount 额外的降价语法： 

markdown: rdiscount
rdiscount: 
  extensions:
    - autolink
    - footnotes
    - smart
    - generate_toc

在_config.yml和中设置 rdiscount 后rake generate，我​​收到如下构建错误：

您看到的问题是由于Jekyll 中的一个错误，该错误已被修复。具体来说，Jekyll 假设如果您指定了，generate_toc那么您也指定toc_token了 ，这是您可以在文档中写入的字符串，以使 Jekyll 插入目录。

更新后的 _config.yml 如下所示：

markdown: rdiscount
rdiscount: 
  extensions:
    - autolink
    - footnotes
    - smart
    - generate_toc
  toc_token: "!TOC"

然后您将!TOC在您希望目录出现的位置插入降价文档。
