ruby-on-rails - Rails 无法生成模型

Question

我正在尝试按照教程 here 学习 Rails .然而，当我到达 the section on creating the model并运行此命令:

bin/rails generate model Article title:string text:text

我遇到了这个错误:

/usr/lib/ruby/vendor_ruby/spring/application.rb:152:in `serve': undefined method `cleanup!' for ActionDispatch::Reloader:Class (NoMethodError)
from /usr/lib/ruby/vendor_ruby/spring/application.rb:131:in `block in run'
from /usr/lib/ruby/vendor_ruby/spring/application.rb:125:in `loop'
from /usr/lib/ruby/vendor_ruby/spring/application.rb:125:in `run'
from /usr/lib/ruby/vendor_ruby/spring/application/boot.rb:18:in `<top (required)>'
from /usr/local/lib/site_ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from /usr/local/lib/site_ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from -e:1:in `<main>'

这是我第二次完成，所以我知道我已经完成了所有步骤。知道我可以在哪里寻找解决方案或知道解决方案是什么吗？这真的让我卡住了。

版本:

• Ubuntu 16.04
• ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]
• gem 2.6.12
• rails 5.1.0

基于 this issue ，你可以运行 spring stop 并尝试再次运行你的命令吗？
