首先，我是web dev，ruby，rails heroku等的新手 . 所以请原谅新手
我在heroku上部署了一个应用程序，并尝试使用paperclip和s3存储资产 . 我遵循了https://devcenter.heroku.com/articles/paperclip-s3，https://github.com/thoughtbot/paperclip/wiki/Paperclip-with-Amazon-S3和https://devcenter.heroku.com/articles/direct-to-s3-image-uploads-in-rails提供的指导原则 . 我使用了figaro宝石 . Paperclip和adminsitrate在开发环境（本地bin）上运行良好 .
这是我的应用程序的Gemfile：
source 'https://rubygems.org'
git_source(:github) do |repo_name|
repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
"https://github.com/#{repo_name}.git"
end

在heroku日志中，我在底部有以下内容：
2018-06-05T15:08:30.157530+00:00 heroku[router]: at=info method=GET path="/admin" host=www.wisetax.fr request_id=3b81377e-d179-4f97-9d21-6bed62b8cb87 fwd="88.165.143.139" dyno=web.1 connect=1ms service=242ms status=500 bytes=1827 protocol=http
我添加并配置application.yml（对于figaro）
The problem is that when I want to get my admin dashboard (I use the gem administrate) on www.wisetax.fr/admin I get the followings:
"We're sorry, but something went wrong If you are the application owner check the logs for more information."
有关完整信息，请注意在发布此问题之前，我遇到了另一个我“修复”（可能不正确）的问题 .
当我git推送heroku master时，我已经中止了rake（rake precompile assets w / messge指的是“环境”） . 我发现修复它的唯一方法是创建一个.env文件并git添加这个文件（我猜它很脏） . 然后我可以推动heroku大师 .
有人可以帮帮我吗？提前谢谢了！
