导轨 4 路由 没有匹配的路由 [GET] "/help"

Question

我不知道我犯了什么错误，这是如此基本的：

本地主机：3000

作为我的根，但如果我输入 localhost：3000/help，我会收到以下错误：

   Started GET "/help" for 127.0.0.1 at 2016-02-09 17:11:37 -0500

  /home/reed/.rubies/ruby-2.1.5/lib/ruby/2.1.0/webrick/server.rb:295:in `block in start_thread'

这是我的routes.rb：

Rails.application.routes.draw do
root 'static_pages#home'
get  'static_pages/help'
get  'static_pages/about'

结束

我在视图/static_pages下有文件帮助.html.erb，以下是文件内容：

    <% provide(:title, "Help") %>
<h1>StaticPages#help</h1>
<p>Find me in app/views/static_pages/help.html.erb</p

这是我的控制器：

class StaticPagesController < ApplicationController
    def home
    end
    def help
    end
end

这和 rails 应用程序一样基本。我不知道我做了什么，但如果你能看到错别字或我犯了错误，请告诉我。谢谢

你的语法有点不对劲。

你有：

Rails.application.routes.draw do
    root 'static_pages#home'
    get  'static_pages/help'
    get  'static_pages/about'
end

它应该是：

Rails.application.routes.draw do
    root 'static_pages#home'
    get  'help' => 'static_pages#help'
    get  'about' => 'static_pages#about'
end
