1.我在ruby-2.0.0 rails-4.0上工作 2.我遵循教程http://ruby.railstutorial.org/chapters/static-pages#top
我跑了＃34;捆绑安装＆＃34;命令。
这是＆＃34;捆绑安装＆＃34;的输出。命令

Use `bundle show [gemname]` to see where a bundled gem is installed.

5.接下来我运行了这个命令  ＆＃34; $ rails生成控制器StaticPages主页帮助--no-test-framework＆＃34;。

根据教程

，输出必须如下所示 
  create  app/controllers/static_pages_controller.rb
   route  get "static_pages/help"
   route  get "static_pages/home"
  invoke  erb
  create    app/views/static_pages
  create    app/views/static_pages/home.html.erb
  create    app/views/static_pages/help.html.erb
  invoke  helper
  create    app/helpers/static_pages_helper.rb
  invoke  assets
  invoke    coffee
  create      app/assets/javascripts/static_pages.js.coffee
  invoke    scss
  create      app/assets/stylesheets/static_pages.css.scss

但是我得到了输出

6.我尝试了教程中的下一个命令＆＃34; $ rails generate controller static_pages ...＆＃34;控制器名为＆＃34; static_pages_controller.rb＆＃34;必须已经生成。
＆＃34; $ rails的输出生成控制器static_pages ...＆＃34;是

但是这个控制器没有生成。请你帮忙吗？

答案 0 :(得分：0)

好的，我没有评论的声誉，但在我看来，就像你在这里输入$：

user@user-Latitude-E6410:~/rais_project/sample_app$ $ rails generate controller static_pages ...
$: command not found

您可能会输入两次。请记住，在Linux上，您不需要每次都输入它。虽然你第二次没有。所以我不知道。

一年前我才开始使用rails。我给你的建议是：

确保您运行的是简易版Linux，例如Ubuntu或Mint。 使用RVM安装。完全按照教程。熟悉终端＆amp; amp;贝壳。 老实说，这看起来像某种配置错误。

我认为您的问题与使用生成控制器的命令无关，而是在教程的后面。

我建议深吸一口气，慢慢地回顾一下教程中的步骤。我认为这只是一个配置问题。 （只是我在猜测。）保持冷静，玩得开心吧！
