Rails无法生成模型

Question

我正在尝试按照这里的教程学习rails .但是,当我进入创建模型的部分并运行此命令时:

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

我收到了这个错误:

/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>'

这是我的第二次经历,所以我知道我已经遵循了所有步骤.我知道在哪里寻找解决方案或知道解决方案是什么？这真让我陷入困境.

版本:

• Ubuntu 16.04

基于此问题,您可以运行spring stop并尝试再次运行命令吗？
