无法加载此类文件 -- bcrypt_ext with devise

Question

我已经使用 devise 在我的 Rails 应用程序中添加了身份验证，一切正常，但是当我尝试注册时出现此错误：

LoadError in Devise::RegistrationsController#create
cannot load such file -- bcrypt_ext

我查看了我的 gemfile，发现 bcrypt gem 丢失了，所以我安装了它，但这并没有解决我的问题

在搜索时，我在某处看到我必须在安装 bcrypt gem 后重新启动服务器，我尝试过，现在当我尝试启动服务器时出现此错误：
