未初始化的常量TZInfo :: InvalidTimezoneIdentifier(NameError) - Rails 4

Question

我正在将Rails 3.2应用程序升级到Rails 4.1.每当我尝试启动控制台或服务器时,我都会遇到此错误:

        ...

不确定是什么导致它,并想知道是否有人有任何建议.我在irb中尝试了这个并且没有遇到任何问题(应该引发错误):

irb(main):001:0> require 'active_support/core_ext/time/zones'
=> true
irb(main):002:0> Time.find_zone!('good')
ArgumentError: Invalid Timezone: f

        from (irb):3
        from C:/Ruby200/bin/irb:12:in `<main>'

Gemfile包括:

ruby "2.0.0"
gem "rails", "~> 4.1.0.beta1"
gem 'tzinfo-data'

编辑(更多信息):似乎包含gem'tzinfo-data'可能会搞砸了什么？当gem在gemfile中时,好像RailsApp::Application.initialize!在environment.rb中调用期间并不需要'tzinfo' .然而,当宝石被移除时,需求正在发生.

Answer 1

tzinfo在初始化应用environment.rb程序之前需要gem来解决我的问题.并没有真正解释一切,但似乎工作

# adding this fixes the issue
require 'tzinfo'

# Initialize the rails application
RailsApp::Application.initialize!

编辑:似乎这是Rails的一个问题:https: //github.com/rails/rails/issues/13553
