Ruby on Rails:rails 生成控制器不起作用 [英] Ruby on Rails : rails generate controller does not work

问题描述

我是 ruby​​ 和 rails 的新手，我在生成控制器时遇到了问题.

I am new to ruby and rails and I am having a problem with generating controllers.

一些上下文:

$ rails -v
Rails 4.1.1

应用已正确创建:

$ rails new test_app
      create
      create  README.rdoc
      create  Rakefile
      create  config.ru
      create  .gitignore
      create  Gemfile
      create  app
[...]
Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.
         run  bundle exec spring binstub --all
* bin/rake: spring inserted
* bin/rails: spring inserted

服务器运行良好:

$ rails server
=> Booting WEBrick
=> Rails 4.1.1 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
=> Ctrl-C to shutdown server
[2014-06-07 11:12:20] INFO  WEBrick 1.3.1
[2014-06-07 11:12:20] INFO  ruby 1.9.3 (2014-02-24) [x86_64-cygwin]
[2014-06-07 11:12:20] INFO  WEBrick::HTTPServer#start: pid=3340 port=3000

我可以浏览默认页面，但是当我尝试进入下一步时，它失败了:

I can browse the default page, but then when I try to go to the next step, it's failing :

$ rails generate controller welcome index

没有任何反应，也没有生成文件.根本没有输出，所以我不知道应该在哪里解决这个问题.

Nothing happens and the files are not generated. There is not output at all so I don't know where I should look to fix the issue.

我已经尝试创建一个全新的应用程序并重新安装 rails，但这无济于事.

I already tried creating a fresh new app and reinstalling rails, but this doesn't help.

推荐答案

尝试运行

spring stop

rails generate 可能无法工作，因为 spring 已经在运行.

rails generate may not work because spring is already running.
