Cloud 9中的Rails教程错误
提问于 2015-04-13 04:41:44
试着让它起作用，但我遇到了麻烦。我正在遵循下面的说明：https://www.railstutorial.org/book/beginning#cha-beginning
我转到1.3.2，然后输入：
rails server -b $IP -p $PORT这会导致此错误，而不是运行WEBrick：

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'

看起来该教程最近刚刚过时了。如果您从更新您的gemfile
gem 'sass-rails', '5.0.1'至
gem 'sass-rails', '5.0.2'然后再次捆绑安装并启动服务器，它应该可以正常工作。
(如果您愿意，也可以通过添加
gem 'sass', '3.4.13'在现有的、未更新的行之前：
gem 'sass-rails', '5.0.1'在您的gemfile中，执行捆绑包安装并启动服务器。不过，我不知道您为什么需要这样做。)
