Question

我是StackOverflow和Rails的新手，所以我希望这不是一个太天真的问题。我正在尝试使用bin / rails服务器在本地运行我的应用程序。当我输入时，我收到以下痕迹：

=> Booting Puma
=> Rails 4.2.5 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

我不相信我可以忽略它（warning: constant ::Fixnum is deprecated When generating new model），因为它不会在本地打开应用程序。

有人可以帮忙吗？

谢谢！本

Ruby 2.4将Fixnum和Bignum统一到一个类Integer中。当Rails（ActiveSupport的core extensions准确）尝试对上述类进行修补时，会发生错误。

这是Rails 5中的fixed，修复程序也被version 4.2.8向后移植到Rails 4.2：

大家好，

我很高兴地宣布Rails 4.2.8已经发布。

这是正式支持的4.2系列的第一个版本   Ruby 2.4。

从4.2.5到Rails 4.2.8，您需要做的只是upgrading Rails。

Ruby 2.4.1 - 警告：不推荐使用constant :: Fixnum
