Question

我刚刚将旧的rails应用程序（3.2.22）升级到rails 4.2.10并且我不确定这是否是正确的地方，但经过几个小时的研究后，我有点难过。 BRAND NEW rails 4.2.10（相同的ruby）项目工作（下面的行为不会发生）但是这个升级的项目在ActiveSupport :: Duration函数的任何实例上都失败了。我在升级中遗漏了什么吗？这是一个宝石问题吗？加载订单？

它不仅仅是Fixnum的任何一个ActiveSupport :: Duration函数

预期行为

irb(main):001:0> 20.days
=> 20 days
irb(main):002:0> 20.days.from_now
=> Wed, 13 Jun 2018 22:35:42 UTC +00:00

实际行为

irb(main):003:0> 20.days

System configuration

Rails版本：4.2.10

Ruby版本：ruby 2.3.1p112

我也尝试在同一个项目上升级到ruby 2.4并且问题仍然存在（似乎与ruby无关）还将项目中的gemfile复制到一个新项目中，看起来没问题

Rails 4.2.10升级TypeError：ActiveSupport :: Duration无法强制转换为Fixnum
