有一个使用 BCrypt 哈希密码的 Ruby on Rails 应用程序，用户模型有

require "BCrypt"

并且gemfile有

gem 'bcrypt-ruby'

这在本地运行时一切正常，但是当我将它部署到我的 Heroku 服务器时，我收到以下错误

我假设问题是No such file to load -- BCrypt (LoadError)但似乎无法修复它，bundle install并且bundle update工作正常，它说 bcrypt-ruby 安装正常。
有什么想法可以解决这个问题吗？我都出来了！

谢谢

问题是大写，因为我在 Windows 上开发，它不关心大小写，但在 Heroku (UNIX) 服务器上它确实如此，我应该使用“bcrypt”而不是“BCrypt”。
