Question

我正在尝试将RSpec测试框架用于rails5。我已经将“ rspec-rails” gem安装到我的gem文件中并安装了它。

这是.gem文件。

group :development, :test do
  gem 'rspec-rails', '~> 3.8'
  gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
end

在运行“ rails generate rspec：install”命令的第二步中，出现以下错误。
错误

application.rb文件

module RSpec
    class Application < Rails::Application
        config.load_defaults 5.2
        config.generators.system_tests = nil
    end
end

../ config / application.rb文件中是否有需要“需要”的内容？

无法生成RSpec：-未初始化的常量RSpec :: Rails :: Application（NameError）
