无法将Rails应用程序部署到Heroku

Question

我在向Heroku部署rails应用程序时遇到了麻烦。 Heroku给我错误消息An error occurred while installing Ruby ruby-2.1.1这让我很困惑，因为我已经完成了将所有内容设置为ruby 2.0.0。 有任何想法吗？ 谢谢！

到目前为止我的步骤：

• 我在这里搜索https://devcenter.heroku.com/articles/ruby-support#supported-runtimes ，查找当前兼容的ruby版本。
• 我在计算机上通过RVM安装了Ruby 2.0.0版本

• 我确保使用此版本： rvm use ruby-2.0.0

• 我将行ruby'2.0.0'添加到App的Gemfile中

• 我确实运行了bundle install （No Error Messages）
• 我确实运行了git push heroku master

Heroku错误消息：

Heroku不支持Ruby 2.1.1。 就像它在错误中所说的那样，你可以在这里找到哪些ruby运行时工作。

快速查看有效的Ruby运行时：1.8.7,1.9.2,1.9.3,2.0.0,2.1.6,2.2.2。
