Rails：遵循 rolify 教程但在 Ruby 解释器中遇到错误

Question

gem 'devise', '~> 4.2'
gem 'rolify', '~> 5.1'
gem 'cancancan', '~> 1.15'
rails 5.0
ruby2.3.0

我正在按照 rolify 教程学习 rolify。 https://github.com/RolifyCommunity/rolify/wiki/Devise---CanCanCan---rolify-Tutorial

我完全按照教程指示完成了每一步。安装和配置后，当我在控制台中移动到 usage 和运行 user = User.new 时，它向我显示了数千行这样的错误。谁能告诉我如何解决这个问题？

我发现可能是Spring Gem触发的bug。

所以我的解决方案是在rails c

之前输入spring stop

或者如果您不需要，只需删除 Gem 文件中的 gem spring。

试试吧！
