我在终端

中尝试了以下cmd

  

bundle exec rails生成rspec：install

但没有运气:(

将以下内容放在我的Gemfile中

group :test, :development do
  gem 'rspec-rails', '~> 3.1.0'
end

Answer 1

可能是Rspec版本不兼容：降级rspec版本或只写：

gem 'rspec-rails'

然后你可以更新它：

bundle update rspec-rails 

Answer 2

我可以使用

创建spec文件夹和spec_helper.rb

<强> rspec --init
