Ruby 绑定器：无法加载命令：rspec

我是Rails新手，我想使用Mac运行Rspec

当我跑步时：

bundle exec rspec spec/00_hello_spec.rb 

我得到以下回应：

请提供有关此问题的任何建议或澄清。另外，我已经在文件系统的各个级别上从根目录向上完成了这项工作。我非常感谢任何澄清，以帮助我走出困境

您是否运行了

rails generate rspec:install

？文件

spec/spec\u helper.rb

是否存在？此文件通常是自动生成的，但如果您可以轻松地手动添加它的话。文件的第一行

spec/00\u hello\u spec.rb

可能表示

需要“spec\u helper”

，而该文件不存在。这就是错误消息告诉你的。>我能够让它工作是什么命令完成的？这种评论——“哦，没关系，我找到了它”——对于以后搜索错误消息后发现这个问题的任何人来说都毫无帮助。
