ruby-on-rails - Rails 不会读取环境变量

Question

Ruby 1.9.3p327、Rails 3.2.9、omniauth 1.1.1、omniauth-google-oauth2、Ubuntu 12.10。

omniauth.rb 初始化器说:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2, ENV['OMNIAUTH_PROVIDER_KEY'], ENV['OMNIAUTH_PROVIDER_SECRET'], {access_type: 'online', approval_prompt: ''}
end

~/.bashrc 说:

### Added for omniauth
export ENV['OMNIAUTH_PROVIDER_KEY']="693094632646.apps.googleusercontent.com"
export ENV['OMNIAUTH_PROVIDER_SECRET']="693126830846.apps.googleusercontent.com"

(我更改了数字，但保留了字符串，以便您明白我的意思。)

我重新启动了我的 Rails 服务器，但当我尝试通过 Google 进行身份验证时，我仍然收到 Missing required parameter: client_id。所以，出于某种原因，Ruby 没有读取这个环境变量，我完全迷路了。

有什么想法吗？提前致谢!

编辑:完整的 .bashrc 如下:

export OMNIAUTH_PROVIDER_KEY="5323094630846.apps.googleusercontent.com"
export OMNIAUTH_PROVIDER_SECRET="693044132846.apps.googleusercontent.com"

PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting

### Added by the Heroku Toolbelt
export PATH="/usr/local/heroku/bin:$PATH"
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

导出时不需要加ENV，这里是~/.bashrc:

export OMNIAUTH_PROVIDER_KEY=693094632646.apps.googleusercontent.com
export OMNIAUTH_PROVIDER_SECRET=693126830846.apps.googleusercontent.com

我认为这行得通:)
