无法连接到服务器：连接被拒绝

标签： ruby-on-rails heroku

我正在使用rails 3.2.13。推送到Heroku时我收到以下错误。 我的应用程序工作正常，我只是想在尝试更新我的heroku应用程序时删除此消息。

对此有何修复？或任何导致冲突的宝石？

GEM FILE：     宝石'轨道'，'3.2.13'

group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'uglifier', '>= 1.0.3'
end

group :development do

end

gem 'heroku-api'
gem 'jquery-rails'
gem 'pg'
gem 'private_pub'

以下错误代码：

您需要通过heroku labs:enable user-env-compile启用其中一个实验室功能，这将使您的应用程序在编译slug时访问环境变量。
