【问题描述】：
我在 Heroku 上部署一个简单的 ruby on rails api 时遇到问题。
当我部署我的应用程序（使用 gitlab CI）时，我有 这个日志：

当我使用邮递员（使用邮递员）获取我的 api URL 时，我有这个日志：
2017-11-26T22:42:44.868503+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/characters" host=wsfcontenders-rails-dev.herokuapp.com request_id=1d0860a2-a26f-42e9-90ab-58213e0357a9 fwd="90.44.177.33" dyno= connect= service= status=503 bytes= protocol=https
所以，我尝试重新启动我的应用程序（重新启动所有 Dynos）：

我的Gemfile：

git_source(:github) do |repo_name|
repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
"https://github.com/#{repo_name}.git"
end

ruby "2.2.8"
有什么想法吗？ :)
谢谢！
