運行rails服務器時沒有'jcode'gem

Question

當我嘗試運行'rails server'時，它給我一個錯誤，說它找不到'jcode'，我認爲jcode是默認的ruby庫。 你們有什麼線索知道發生了什麼？

Answer 1

聽起來像你使用的庫沒有爲Ruby 1.9更新。

Ruby> = 1.9沒有jcode，它是一個處理日語（EUC/SJIS）字符串的模塊，因爲它本身支持unicode。

您可能希望看到的庫的更新版本可用，否則，你可以看看源並找到它需要jcode，並與

require 'jcode' if RUBY_VERSION < '1.9' 

Answer 2

我們應該檢查的lib更換在gdata gem文件下顯示的文件夾。

加入這一行：

require 'jcode' if RUBY_VERSION < '1.9' 

在lib/gdata.rb文件。

Answer 3

其他的解決方案，把這個在您的Gemfile：

gem 'gdata_19', '1.1.5' 
gem 'contacts', :git => 'git@github.com:eofferma/contacts.git'
