当我尝试启动我的 rails 控制台时，我收到以下错误，
/usr/lib/ruby/vendor_ruby/rails/railtie/configuration.rb:95:in `method_missing': undefined method `load_defaults' for #<Rails::Application::Configuration:0x000055af3aee4550> (NoMethodError)

我该如何解决这个问题？
根据给出的错误堆栈，似乎您在应用程序加载期间加载配置时遇到了问题。
下面提到的链接也解决了同样的问题。
尝试在 Heroku 上部署应用程序时出现错误"找不到的方法"load_defaults">
希望对您有所帮助！！
