运行rails服务器时没有'jcode'gem

Question

当我尝试运行'rails server'时，它给我一个错误，说它找不到'jcode'，我认为jcode是默认的ruby库。 你们有什么线索知道发生了什么？

Answer 1

听起来像你使用的库没有为Ruby 1.9更新。

Ruby> = 1.9没有jcode，它是一个处理日语（EUC/SJIS）字符串的模块，因为它本身支持unicode。

您可能希望看到的库的更新版本可用，否则，你可以看看源并找到它需要jcode，并与

require 'jcode' if RUBY_VERSION < '1.9' 

Answer 2

我们应该检查的lib更换在gdata gem文件下显示的文件夹。

加入这一行：

require 'jcode' if RUBY_VERSION < '1.9' 

在lib/gdata.rb文件。

Answer 3

其他的解决方案，把这个在您的Gemfile：

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