ruby-on-rails – 用于Ruby on Rails的Twitter Gem无法正常工作.

我试图让 Twitter gem版本5.1.1在我的应用程序中工作,但我遇到配置问题.我正在运行rails 4和Ruby 2.0.0.在我的Gemfile中,我列出了“gem’twitter’”,并通过捆绑包安装了它.根据文档,我在config / initializers / twitter_credentials.rb中创建了一个初始化文件.该文件看起来像这样(虽然我的密钥和秘密充满了来自twitter的信息)：

require 'twitter'

client = Twitter::REST::Client.new do |config|
  config.consumer_key        = "YOUR_CONSUMER_KEY"
  config.consumer_secret     = "YOUR_CONSUMER_SECRET"
  config.access_token        = "YOUR_ACCESS_TOKEN"
  config.access_token_secret = "YOUR_ACCESS_SECRET"
end

当我尝试在rails控制台中使用客户端时,这是我收到的错误消息：

2.0.0p353 :001 > client.update("I'm tweeting with @gem!")
NameError: undefined local variable or method `client' for main:Object
from (irb):1

from bin/rails:4:in `require'
from bin/rails:4:in `<main>'

知道问题是什么吗？
