rails 5 - 无法生成 rspec:install

Question

我正在尝试使用 Rails 构建 restful api

我正在按照博客链接教程进行锻炼

https://scotch.io/tutorials/build-a-restful-json-api-with-rails-5-part-one

但是当我运行以下命令时

rails generate rspec:install

它会产生以下错误

我尝试了一些堆栈溢出的相关解决方案，但没有一个有效。

几天前我遇到了同样的问题。我必须做的是从我的机器上删除所有版本的 RSpec，然后运行 ​​bundle install。这安装了最新版本的 RSpec，之后一切都很好。
