似乎无法让我的Rails服务器运行于云c9.io服务

Question

我似乎无法让我的服务器在尝试尝试更新Gemfile并执行捆绑更新和捆绑包安装命令之后尝试在c9.io上运行抓住sass rails的宝石。

`master) $ rails server -b $IP -p $PORT 
/usr/local/rvm/gems/ruby-2.2.1/gems/bundler-1.11.2/lib/bundler/runtime.rb:80:in `rescue in block (2 levels) in require': There was an error while trying to load the gem 'sass-rails'. (Bundler::GemRequireError)

以我目前的宝石是以下几点：

source 'https://rubygems.org' 


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails' 
gem 'rails' 
# Use sqlite3 as the database for Active Record 

# Use SCSS for stylesheets 
gem 'sass-rails' 
# Use Uglifier as compressor for JavaScript assets 
gem 'uglifier' 
# Use CoffeeScript for .coffee assets and views 
gem 'coffee-rails' 
# See for more supported runtimes 
# gem 'therubyracer', platforms: :ruby 

# Use jquery as the JavaScript library 
gem 'jquery-rails' 
# Turbolinks makes following links in your web application faster. Read more: 
gem 'turbolinks' 
# Build JSON APIs with ease. Read more: 
gem 'jbuilder' 
# bundle exec rake doc:rails generates the API under doc/api. 
gem 'sdoc', '0.4.0', group: :doc 

# Use ActiveModel has_secure_password 
# gem 'bcrypt', '~> 3.1.7' 

# Use Unicorn as the app server 
# gem 'unicorn' 

# Use Capistrano for deployment 
# gem 'capistrano-rails', group: :development 

group :development, :test do 
    # Call 'byebug' anywhere in the code to stop execution and get a debugger console 
    gem 'sqlite3' 
    gem 'byebug' 

    # Access an IRB console on exception pages or by using <%= console %> in views 
    gem 'web-console' 

    # Spring speeds up development by keeping your application running in the background. Read more: 
    gem 'spring' 
end 

Answer 1

您的Gemfile更改为：

source 'https://rubygems.org' 

gem 'rails',  '4.2.2' 
gem 'sass-rails', '5.0.2' 
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 

group :production do 
    gem 'pg',    '0.17.1' 
    gem 'rails_12factor', '0.0.2' 
end 

运行：

$ bundle install --without production 

然后确保你是你的toy_app目录，运行：

$ rails server -b $IP -p $PORT
