ruby-on-rails - 尽管模板存在，但 Rails 持久性 "No template for interactive request"

Question

我在使用 Rails 时遇到了这个问题。我遵循了基本指南:

rails new blog-2

rails g controller 主页索引

现在我有了包含所有文件的标准文件夹，以及 view/homepage 中的 Controller Homepage 和 index.html.erb文件夹

接下来我将路由更改为

Rails.application.routes.draw do

  root 'homepage#index'
end

This is how my directory looks like

我没有编辑 homepage_controller.rb 和 index.html.erb

But I keep getting this error at localhost:3000

我试过很多方法，全部卸载，重新安装。绝望的我，我什至重置了我的笔记本电脑。重新安装一切，但无济于事。请railers高手帮忙，谢谢!!

编辑:这是我根据要求执行的索引操作

class HomepageController < ApplicationController
  def index
  end
end

编辑:下面是我运行 rails s

时的错误

Processing by HomepageController#index as HTML
Completed 406 Not Acceptable in 16ms (ActiveRecord: 0.0ms | Allocations: 1996)

Answer 1

我在 Windows 10 上遇到了完全相同的问题，我终于找到了解决方案。我使用 gitbash 导航到项目文件夹并运行 rails s。在尝试了我在互联网上阅读的所有内容(重启计算机、重新安装 rails、回滚到以前的版本、重新配置路由、重命名 html.erb 文件...)之后，我仍然遇到同样的问题。

有一天，我决定在 Windows CMD 上运行 rails s 并且它得到了修复!我的所有代码 - Controller 、index.html.erb 文件等都完全相同。
