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

我正在將Rails 3.2應用程序升級到Rails 4.1。每當我嘗試雖然啓動控制檯或服務器，我碰到過這樣的錯誤：未初始化的常量TZInfo :: InvalidTimezoneIdentifier（NameError） - Rails 4

不能確定是什麼導致了它，並想知道如果任何人有任何意見。我在IRB嘗試這樣做，並沒有遇到任何問題（拋出一個錯誤，因爲它應該是）：

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 C:/Ruby200/lib/ruby/gems/2.0.0/gems/activesupport-4.1.0.beta1/lib/a 
ctive_support/core_ext/time/zones.rb:71:in `rescue in find_zone!' 
     from C:/Ruby200/lib/ruby/gems/2.0.0/gems/activesupport-4.1.0.beta1/lib/a 
ctive_support/core_ext/time/zones.rb:55:in `find_zone!' 
     from (irb):3 
     from C:/Ruby200/bin/irb:12:in `<main>'

的Gemfile包括：

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

編輯（一些更多的信息）：看起來好像包含gem'tzinfo-data'可能會搞砸一些東西？當gem位於gemfile中時，看起來好像在environment.rb的RailsApp::Application.initialize!調用期間'tzinfo'不會被需要。但是，當寶石被移除時，需求正在發生。

在初始化應用程序environment.rb之前需要tzinfo gem修復了我的問題。並沒有真正解釋一切，但似乎工作

# adding this fixes the issue 
require 'tzinfo' 

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

編輯：看來這是使用Rails的一個問題： https://github.com/rails/rails/issues/13553

-1

這爲我工作：

gem uninstall tzinfo 
#select 'All versions' 
gem install tzinfo 
rails c
