在开发的早期阶段，我安装了 rack-mini-profiler gem 以将新 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 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。我尝试删除 heroku 中的应用程序并启动一个新应用程序，当我推送时，我遇到了同样的错误。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 文件并查找了关键字“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任何它的踪迹时，它仍然给我一个未初始化的常量。提前感谢您的帮助！
