rails-4中的TZInfo::DataSourceNotFound

Question

请帮助我解决此错误。

我在Gemfile中添加了"gem 'paperclip', '~> 3.0'“并运行命令bundle install。

安装捆绑包后，当我键入"rails g controller user"并按enter键时，我收到以下错误。

错误：

我的Gemfile包含以下代码。

source 'https://rubygems.org'


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.7'

# Use sqlite3 as the database for Active Record

只需将此代码放入您的应用程序终端：

gem install tzinfo-data

然后将gemfile行更改为：

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

然后再次在您的终端中：

bundle update

这将直接解决问题。
