我正在尝试从ruby应用程序执行POST请求,我收到以下错误.

这是代码:

 def action_reply(token,action_id,reply_text)
  require 'uri'
  require 'net/http'
  require 'net/https'

  @reply = { 'ACTION_ID' => action_id, 'text' => reply_text }.to_json
  #A token is required to do this post
  @token_url = 'https://example.com/reply?oauth_token=' + token
  uri = URI.parse(@token_url)
  response = Net::HTTP.post_form(uri,@reply)
end

我在最后一步中遇到错误:

 NoMethodError (undefined method `map' for #<String:0x000000063798e8>)

知道为什么会这样吗？

谢谢!

我正在尝试将现有应用程序迁移到ruby 2.0 + rails 4.0,到目前为止一切正常,但是当我尝试安装设备时:

rails generate devise:install

我收到以下错误:
