Octopress 如何启用RDisont额外降价'；生成toc'；八月初

我试图通过配置_config.yml，使Octopress使用默认的标记解析器RDisont（2.1.7）生成TOC，但它不起作用，

rake generate

失败。
我尝试了答案，但对我也不起作用。
因此，我想知道是否有办法配置Octopress RDisont额外的标记语法，如下所示：

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

在_config.yml中设置rdisont并

rake generate

后，我得到一个构建错误，如下所示：

构建失败

您看到的问题是由于。具体地说，Jekyll假设如果您指定

generate_toc

，那么您还可以指定

toc_token

，这是您可以在文档中写入的字符串，以使Jekyll插入目录

更新的_config.yml如下所示：

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

---

然后您将插入

！TOC

在您的降价文档中，位于您希望目录出现的位置。

我认为该配置块是正确的。也许您可以提供当

rake generate

失败时发生的错误的相关信息？@DavidFoster，谢谢您的回复。我在上面添加了错误信息。您是否进行了其他设置或修补程序以使配置正常工作？
