Question

我在Heroku上有一个制作应用程序 - productionapp.heroku.com

所以，我按照步骤为它创建了一个临时应用程序：

1. heroku create stagingapp  --remote staging
2. heroku config:add RACK_ENV=staging  --app stagingapp
3. heroku addons:add mongohq:free  --app stagingapp
4. In config/mongoid.yml -
   add
     staging:
       uri: <%= ENV['MONGOHQ_URL'] %>
5. cp config/environments/production.rb config/environments/staging.rb
6. Add the MONGOHQ_URL in the mongohq.com connection.
6. git push staging master

暂存应用程序不断崩溃，并带有以下回溯：

我一次又一次地尝试并重试这些步骤并最终遇到同样的错误。如果你能帮帮我的话会很棒！

我猜你没有正确添加配置，因为这是在mongoid中失败的行

YAML.load(ERB.new(File.read(config_file)).result)[Rails.env].values.flatten.any?

Heroku登台应用程序崩溃（无法读取环境/ staging.rb）
