在开发的早期阶段，我安装了 rack-mini-profiler gem 来将新 Rails 应用程序中烦人的计时器移到底部。然后当我尝试推送到heroku时，我遇到了这个错误。然后我删除了我的 Gemfile 中的 gem，运行了 bundle install，还删除了 config/initializers 中的 rack mini profiler 文件。仍然得到同样的错误。我尝试在heroku中删除应用程序并启动一个新应用程序，当我推送时，我得到了同样的错误。现在我什至删除了实际的 gem，但仍然是同样的错误。我什至扫描了 rails 文件并寻找关键字“rack”，但我什么也没找到。我不知道为什么当我现在在我的应用程序中找不到它的任何痕迹时它仍然给我一个未初始化的常量。提前感谢您的帮助！
