Jekyll site.posts返回空

我正试图建立一个个人网站使用杰基尔。我选择了杰基尔，是因为我遵循了迈克尔·哈特尔的《学会足够的CSS和布局危险》的丰富教程

我正试图在我的主页上显示一些精选的博客文章

My_posts文件夹位于根目录中，文件名采用正确的DD-MM-yyy-title.md格式，日期发生在过去

我使用输出site.posts

{{ site.posts.size }}
{{ site.posts | inspect }}

它们输出“0”和“[]”，因此数组看起来是空的

回购协议可在以下位置获得：

非常感谢您的帮助

经过进一步调试后，似乎与kramdown gem模块存在冲突。根据另一篇SO帖子的想法，我在注释掉_config.yaml中的“collections_dir”行后看到了这个错误。尝试生成时，它给了我以下错误：
