我有一个基于Jekyll 3.0.1 based on this Kasper theme的博客，并进行了一些修改。我已经删除了所有帖子，但其中一个是为了降低我遇到的问题的自由度。当我包含一个＆＃34;摘录＆＃34;在帖子的YAML前端内部标记和它的值，但当我删除它时，我得到一个错误（如下所示）。我尝试过使用＆＃34; excerpt_separator＆＃34; _config.yml文件中的标记和值，并将分隔符放在帖子中，但这没有帮助。只是为了它的地狱我甚至提出了默认＆＃34;摘录＆＃34; _config.yml中的标记和值，这也没有帮助。在我看来，我的Jekyll安装不再适当地自动生成摘录，因为当我手动包含一个＆＃34;摘录＆＃34;在帖子的YAML前面的事情。

_plugins/rssgenerator.rb第55行出现问题。
item.description = parser.convert(post.excerpt)
应该是：
item.description = parser.convert(post.to_liquid['excerpt'])
删除它并使用标准的jekyll文件生成您的Feed（find it here）。
在_config.yml中添加：
excerpt_separator: "<!--excerpt-->"
你的帖子：
