如何解决Jekyll site.posts返回空
我正在尝试使用Jekyll建立个人网站。我选择了Jekyll，方法是按照迈克尔·哈特尔（Michael Hartl。
我试图在我的主页上显示一些博客文章。
我的_posts文件夹位于根目录中，文件名具有正确的DD-MM-YYYY-title.md格式，并且日期是过去的日期。
我使用以下方式输出了site.posts
{{ site.posts.size }}
{{ site.posts | inspect }}
它们输出“ 0”和“ []”，因此看起来数组为空。

非常感谢您的帮助！
解决方法
经过更多调试后，似乎与kramdown gem模块发生了冲突。遵循另一篇SO帖子的想法，从_config.yaml中注释掉了“ collections_dir”行后，我看到了错误。尝试生成时，它给了我这个错误：

因此，我卸载并重新安装了Ruby＆Jekyll，并在_config.yaml中将“ collections_dir”行注释掉。现在正在生成帖子。
