TZInfo :: DataSourceNotFound in rails-4

Question

請幫我解決這個錯誤。

我在Gemfile中添加了「gem 'paperclip', '~> 3.0'」並運行命令bundle install。

安裝軟件包後，當我輸入"rails g controller user"並回車時，我收到以下錯誤。

錯誤：

請幫我找出解決方案。提前致謝。在終端

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

然後再：

只是把這個在你的應用終端：

gem install tzinfo-data 

然後更改的Gemfile線

bundle update
