未初始化的常量TZInfo :: InvalidTimezoneIdentifier（NameError） – Rails 4
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：
C:/Ruby200/lib/ruby/gems/2.0.0/gems/activesupport-4.1.0.beta1/lib/active_support /core_ext/time/zones.rb:70:in `rescue in find_zone!': uninitialized constant TZI nfo::InvalidTimezoneIdentifier (NameError) 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 C:/Ruby200/lib/ruby/gems/2.0.0/gems/activesupport-4.1.0.beta1/lib/a ctive_support/railtie.rb:20:in `block in ' from C:/Ruby200/lib/ruby/gems/2.0.0/gems/railties-4.1.0.beta1/lib/rails/ initializable.rb:30:in `instance_exec' from C:/Ruby200/lib/ruby/gems/2.0.0/gems/railties-4.1.0.beta1/lib/rails/ initializable.rb:30:in `run' from C:/Ruby200/lib/ruby/gems/2.0.0/gems/railties-4.1.0.beta1/lib/rails/ initializable.rb:55:in `block in run_initializers' from C:/Ruby200/lib/ruby/2.0.0/tsort.rb:150:in `block in tsort_each' from C:/Ruby200/lib/ruby/2.0.0/tsort.rb:183:in `block (2 levels) in each _strongly_connected_component' from C:/Ruby200/lib/ruby/2.0.0/tsort.rb:219:in `each_strongly_connected_ component_from' from C:/Ruby200/lib/ruby/2.0.0/tsort.rb:182:in `block in each_strongly_c onnected_component' from C:/Ruby200/lib/ruby/2.0.0/tsort.rb:180:in `each' from C:/Ruby200/lib/ruby/2.0.0/tsort.rb:180:in `each_strongly_connected_ component' from C:/Ruby200/lib/ruby/2.0.0/tsort.rb:148:in `tsort_each' from C:/Ruby200/lib/ruby/gems/2.0.0/gems/railties-4.1.0.beta1/lib/rails/ initializable.rb:54:in `run_initializers' from C:/Ruby200/lib/ruby/gems/2.0.0/gems/railties-4.1.0.beta1/lib/rails/ application.rb:285:in `initialize!' from C:/Ruby200/lib/ruby/gems/2.0.0/gems/railties-4.1.0.beta1/lib/rails/ railtie.rb:194:in `public_send' from C:/Ruby200/lib/ruby/gems/2.0.0/gems/railties-4.1.0.beta1/lib/rails/ railtie.rb:194:in `method_missing' from C:/sites/RailsApp/config/environment.rb:5:in `' ... 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中尝试了这个并没有遇到任何问题（因为它应该是错误）：

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’可能会弄乱一些东西？ 当gem在gemfile中时，好像在RailsApp::Application.initialize!期间不需要’tzinfo’ RailsApp::Application.initialize! 在environment.rb中调用。 然而，当gem被移除时，需求正在发生。
在environment.rb初始化应用程序之前需要tzinfo gem为我解决了这个问题。 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
这对我有用：
gem uninstall tzinfo #select 'All versions' gem install tzinfo rails c
