主页上没有使用Jekyll呈现帖子

我想帮助理解为什么我的帖子没有出现在我的主页上。它在本地和GitHub页面上不能正常工作。

我有一些测试帖子 _posts 文件夹(即。 2017-11-22-a-post-about-my-research.markdown 和 2014-11-28-markdown-and-html.md )

下面是这些帖子的一个示例

--
layout: post
title: Feature images
feature-img: "assets/img/sample_feature_img.png"
---
This is an example of a post which includes a feature image specified in the front matter of the post. The feature image spans the full-width of the page, and is shown with the title on permalink pages.

服务器启动,但帖子不在主页上。

另一方面,我可以看到并打开 tags 页

我的项目结构是

我的gem文件如下所示:

source "https://rubygems.org"

# Hello! This is where you manage which Jekyll version is used to run.
# When you want to use a different version, change it below, save the
# file and run `bundle install`. Run Jekyll with `bundle exec`, like so:
#
#     bundle exec jekyll serve
#
# This will help ensure the proper Jekyll version is running.
# Happy Jekylling!
gem "jekyll", "~> 3.6.2"

# This is the default theme for new Jekyll sites. You may change this to anything you like.
# gem "minima", "~> 2.0"
gem "jekyll-theme-type"

# If you want to use GitHub Pages, remove the "gem "jekyll"" above and
# uncomment the line below. To upgrade, run `bundle update github-pages`.
# gem "github-pages", group: :jekyll_plugins

# If you have any plugins, put them here!
group :jekyll_plugins do
  gem "jekyll-feed", "~> 0.6"
  gem "jekyll-paginate"
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
