这很好用：
<% blog.articles.each_with_index do |article, i| %>
<h2><%= link_to article.title, article %> <span><%= article.date.strftime('%b %e') %></span></h2>
<%= article.body %>
<% end %>
这不是：
<% blog.articles.each_with_index do |article, i| %>
<h2><%= link_to article.title, article %> <span><%= article.date.strftime('%b %e') %></span></h2>
<%= article.summary %>
<% end %>
关于该摘要的某些内容会引发错误：
TypeError: type mismatch: String given

依旧......
这是我的config.rb中关于博客gem的部分：
activate :blog do |blog|
# This will add a prefix to all links, template references and source paths
# blog.prefix = "blog"
# blog.permalink = "{year}/{month}/{day}/{title}.html"
# Matcher for blog source files
blog.sources = "posts/{year}-{month}-{day}-{title}.html"
# blog.taglink = "tags/{tag}.html"
# blog.layout = "layout"
blog.summary_separator = "==="
blog.summary_length = 250
# blog.year_link = "{year}.html"
# blog.month_link = "{year}/{month}.html"
# blog.day_link = "{year}/{month}/{day}.html"
# blog.default_extension = ".markdown"
blog.tag_template = "tag.html"
blog.calendar_template = "calendar.html"
# Enable pagination
blog.paginate = true
blog.per_page = 10
blog.page_link = "page/{num}"
end
# activate :directory_indexes
我的宝石文件：
``` 来源＆＃39; http://rubygems.org＆＃39;
gem＆＃34; middleman＆＃34;，＆＃34;〜＆gt; 4.1.0＆＃34; 宝石＆＃34;中间人博客＆＃34; gem＆＃34; middleman-livereload＆＃34; gem＆＃39; middleman-autoprefixer＆＃39;
gem＆＃34; builder＆＃34;，＆＃34;〜＆gt; 3.0＆＃34; ```
我哪里出错？

只是预感，但blog.summary_separator = "==="看起来像麻烦制造者。
尝试另一个不能被错误地解释为比较运算符的字符串，看看它是否有效。
也许试试blog.summary_separator = /(READMORE)/
不要忘记在帖子文件中进行更改。 （忘记那种东西是让我经常追逐我的尾巴的原因。）

您实际上不需要取消注释config.rb中的两行：
blog.summary_separator = "==="
blog.summary_length = 250
尝试在下面添加此行
<%= article.summary %>
<%= link_to 'Read more…', article %>
