window下rails4.1 发生TZInfo::DataSourceNotFound 错误 - smallbottle

在官网上学习rails 4.1 ，启动rails server之后发生了如下错误

$ rails server
Booting WEBrick
Rails 4.1.0 application starting in development on ....
Exiting
c:/RailsInstaller/Ruby2.0.0/lib/ruby/gems/2.0.0/gems/tzinfo-1.1.0/lib/tzinfo/data_source.rb:199:
in `rescue in create_default_data_source':
No timezone data source could be found. To resolve this, either install
TZInfo::Data (e.g. by running `gem install tzinfo-data`) or specify a zoneinfo
directory using `TZInfo::DataSource.set(:zoneinfo, zoneinfo_path)`.
(TZInfo::DataSourceNotFound)
from c:/RailsInstaller/Ruby2.0.0/lib/ruby/gems/2.0.0/gems/tzinfo-1.1.0/lib/tzinfo/data_source.rb:196:
in `create_default_data_source'

给出了解决方法，安装tzinfo-data，在运行命令gem install tzinfo-data之后，还是这个错误。

原因是因为64位操作系统，打开创建的rails应用下的gemfile文件，

找到gem 'tzinfo-data', platforms: [:mingw, :mswin]

改为gem 'tzinfo-data', platforms: [:mingw, :mswin , :x64_mingw]，

然后运行bundle update，即可。
