我試圖使用Feedzirra來解析RSS feed， m不能同時擁有所需的有效支持寶石。它告訴我，兩個版本的activesupport之間有衝突。我有積極的支持（3.2.3）和feedzirra（0.1.3）。無法激活feedzirra-0.1.3，因爲activesupport-3.2.3與有效支持（〜> 3.1.1）衝突（Gem :: LoadError）
這是我的代碼開頭：
require 'rubygems'
require 'simple-rss'
require 'open-uri'
require 'json'
require 'rest-client'
require 'digest/sha1'
require 'mysql2'
require 'active_record'
這裏是當我運行該文件，我得到的錯誤。

任何想法如何解決這個問題？真的很喜歡使用這顆寶石。
