未初始化的常量 Doorkeeper::Application (NameError)

uninitialized constant Doorkeeper::Application (NameError)

我正在尝试扩展 Doorkeeper::Application 模块以在 config/initializer/doorkeeper_patch.rb 中添加一些额外的验证和关系。 但我收到此错误:

uninitialized constant Doorkeeper::Application (NameError)

我的代码(config/initializer/doorkeeper_patch.rb):

Doorkeeper::Application.class_eval do
    ...
end

我的 Gemfile:
