Errno::ENOENT 尝试在云 9 上启动 rails 服务器时

Question

当运行下面代码块中显示的命令时，我也得到以下错误显示

 theoneinskane:~/workspace/toy_app $ rails server -b $IP -p $PORT

我是运行 ruby 2.2.1 和 rails 4.2.2，我加载的 gem 文件如下所示：

    source 'https://rubygems.org'

gem 'rails',                   '4.2.2'
gem 'bcrypt',                  '3.1.7'
gem 'faker',                   '1.4.2'
gem 'carrierwave',             '0.10.0'
gem 'mini_magick',             '3.8.0'
gem 'fog',                     '1.36.0'
gem 'will_paginate',           '3.0.7'
gem 'bootstrap-will_paginate', '0.0.10'
gem 'bootstrap-sass',          '3.2.0.0'
gem 'sass-rails',              '5.0.2'
gem 'uglifier',                '2.5.3'

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 :test do
  gem 'minitest-reporters', '1.0.5'
  gem 'mini_backtrace',     '0.1.3'
  gem 'guard-minitest',     '2.3.1'
end

group :production do
  gem 'pg',             '0.17.1'
  gem 'rails_12factor', '0.0.2'
  gem 'puma',           '2.11.1'
end

尽管进行了广泛的搜索，但我似乎无法弄清楚出了什么问题。如您所知，我是运行教程，但找不到太多帮助。我之前对 2 个小应用程序执行过完全相同的步骤，但没有出现负面结果。对此的任何帮助将不胜感激。我确定这是我所缺少的非常简单的东西

Answer 1

我刚刚实际解决了这个问题。但也许答案可以帮助其他人。尽管四处搜索，我还没有尝试过一件非常基本的事情，那就是关闭 Cloud 9 IDE 中的终端 window，然后打开一个新的 window 并启动 rails服务器。这样做，错误消息不再出现
