Question

我是Ruby on Rails的新用户，我一直在关注官方入门。平台：Windows 10
Ruby 2.2.4
Rails 4.2.5.2
我在做什么：

rails new myapp
cd myapp
捆绑安装
rails服务器

然后我收到此错误：

我已经尝试卸载debug_inspector并在之后运行bundle install，但问题仍然存在。

有人可以帮我吗？

Answer 1

如果它仍然是实际的。尝试将debug_inspector添加到Gemfile中。

Answer 2

您需要在启动rails服务器之前捆绑gem。请遵循以下步骤：

rails new myapp
cd myapp
bundle install
rails server
