我的 config.ru

# config.ru
require "./app"
run Sinatra::Application

我的应用程序.rb

require 'rubygems'
require "sinatra"
require "sass"
require "sinatra/activerecord"
require 'sassy-buttons'

set :database, "sqlite3:///blog.db"

get '/styles.css' do
    scss :styles
end

configure do
  set :show_exceptions, false
end

在我的 Gemfile 中，我确实包含了 gem "sass" and the gem "sassy-buttons"

在我的样式表上

$mainColor:#002b36;
$secColor:#eee;

@import "sassy-buttons"

body{
background: $secColor;
}

标签： gem sass sinatra

【解决方案1】：

问题可能与 sass 版本有关，似乎类似的问题已经在 Why does "compass watch" say it cannot load sass/script/node (LoadError)? 中描述过，因此在您的 Gemfile 中指定 sass 版本或卸载并重新安装可能会有所帮助
