"uninitialized constant Sass::Script (NameError)"
我首先更改了我的 Gemfile（我删除了评论以使文本更短）：
source 'https://rubygems.org'
gem 'rails', '4.2.0'
gem 'sqlite3'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
group :development, :test do
gem 'byebug'
gem 'web-console', '~> 2.0'
gem 'spring'
end
至：
source 'https://rubygems.org'
gem 'rails', '4.2.0'
gem 'sass-rails', '5.0.1'
gem 'uglifier', '2.5.3'
gem 'coffee-rails', '4.1.0'
gem 'jquery-rails', '4.0.3'
gem 'turbolinks', '2.3.0'
gem 'jbuilder', '2.2.3'
gem 'sdoc', '0.4.0', group: :doc
group :development, :test do
gem 'sqlite3', '1.3.9'
gem 'byebug', '3.4.0'
gem 'web-console', '2.0.0.beta3'
gem 'spring', '1.1.3'
end
现在，当我尝试使用 rails server -b $IP -p $PORT 运行 rails 服务器时，我收到以下错误消息：

我在更改 Gemfile 之前尝试了 运行 连接服务器，并且它有效，所以这一定是因为新的更改。我也知道它说的错误 ruby-2.1.5，在我的 Gemfile 中我输入了 4.2.0 但我不知道如何更改它，或者这是否是问题所在？我试图在源代码行下添加 ruby '2.1.5'，没有任何改变。我也将 'rails', '4.2.0' 更改为 2.1.5 但更新失败告诉我 Could not find gem 'rails (= 2.1.5) ruby' in the gems available on this machine.

使用sass-rails v 5.0.2+。这应该可以解决您的问题。所以在 gem 文件中更改：
gem 'sass-rails', '5.0.3'
或
gem 'sass-rails', '5.0.2'
更新：
由于 link 现在已经关闭，所以这个问题实际上是 gem 版本 5.0.1 所以只是 运行:
bundle update sass-rails
这最终会让您 saas-rails gem 更新到最新版本。或者您可以按照上面指定的方式在 gem 文件中输入版本。
