Question

我正在拔出我的头发试图在DH的VPS上启动一个简单的应用程序。

第1步：创建测试应用

$ rails new test app

第2步：修改了config / environment.rb：

require File.expand_path('../application', __FILE__)

if ENV['RAILS_ENV'] == 'production'  # don't bother on dev
  ENV['GEM_PATH'] = '/home/feebzee/.gems' + ':/usr/lib/ruby/gems/1.8'
end

# Initialize the rails application
Testapp::Application.initialize!

应用程序在端口3000上使用webrick正常运行。但是如果我让乘客加载它，我就会到达Rails Welcome Aboard页面，即使点击链接显示应用程序环境也会返回错误。

我已附上以下错误消息，以方便您的观看。提前谢谢，去RoR！： - ）

Answer 1

您是否为您正在使用的环境安装了bundler gem？

Answer 2

WEBrick默认情况下以开发模式运行，但乘客默认以生产模式运行。

以下配置：

if ENV['RAILS_ENV'] == 'production'  # don't bother on dev
  ENV['GEM_PATH'] = '/home/feebzee/.gems' + ':/usr/lib/ruby/gems/1.8'
end

...意味着您在运行乘客时尝试加载一个宝石，而不是在使用WEBrick时 - 假设您没有明确指定环境。

尝试运行bundle install。
