ruby-on-rails - rails 上未定义的方法 `load_defaults' 生成迁移和 rails 控制台

Question

运行时出现此错误：rails generate migration AddRoleToBuyer role:integer

错误：

/usr/lib/ruby/vendor_ruby/rails/railtie/configuration.rb:95:in `method_missing': undefined method `load_defaults' for #<Rails::Application::Configuration:0x000055e8c09a10d8> (NoMethodError)

应用程序和 rspec 测试运行没有问题，但迁移不起作用。

编辑：当我跑步时rails console也会发生这种情况。
