ruby-on-rails - Rails 4.1:Rails:Module的未定义方法 `application'

Question

因此，我试图在Hostgator上托管Rails 4.1，并且在设置rake db:migrate后在远程rails目录中运行database.yml时遇到以下错误:

WARNING: 'require 'rake/rdoctask'' is deprecated.  Please use 'require 'rdoc/task' (in RDoc 2.4.2+)'    instead.
    at /usr/lib/ruby/gems/1.8/gems/rake-0.9.2.2/lib/rake/rdoctask.rb
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!

我认为这可能是在说rails-2.3.18，即使我的rails 4.1在Gemfile中(或者在我开发应用程序时是我本地计算机上的版本)。但是我仍然对如何做感到困惑。

这是我的Gemfile:

 source 'https://rubygems.org'

gem 'rails', '4.0.4'

gem 'haml'
gem 'haml-rails'
gem 'bootstrap-sass', '~> 3.1.1'

gem 'sqlite3'

gem 'sass-rails', '~> 4.0.2'

gem 'uglifier', '>= 1.3.0'

gem 'coffee-rails', '~> 4.0.0'


gem 'stripe', :git=> 'https://github.com/stripe/stripe-ruby'

gem 'jquery-rails'

gem 'turbolinks'

gem 'jbuilder', '~> 1.2'

group :doc do
  gem 'sdoc', require: false
end

不幸的是，截至目前，Hostgator服务器环境不支持rails 4 applications(并且要启动并运行Rails 3应用程序很痛苦)。您将不得不修改您的应用程序以使其与Rails 2.3.8(与ruby 1.8.7兼容)，或寻求更灵活的托管选项。 (几个月前我经历了同样的事情...)
