Ruby on rails 否'；jcode'；运行rails服务器时的gem

当我尝试运行“rails服务器”时，它会给我一个错误，说它找不到“jcode”，我认为jcode是默认的ruby库。 你们知道发生了什么事吗

听起来你正在使用的库没有针对Ruby 1.9进行更新

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

您可能希望看到有一个更新版本的库可用，否则您可以查看源代码，找到它需要jcode的地方，并将其替换为

require 'jcode' if RUBY_VERSION < '1.9'

如果RUBY_版本<'1.9'，则需要'jcode'

---

我们应该检查gdatagem文件下的lib文件夹

添加此行：

require 'jcode' if RUBY_VERSION < '1.9'

如果RUBY_版本<'1.9'，则需要'jcode'

---

在

lib/gdata.rb

文件中。

其他解决方案中，将其放入GEM文件中：

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

---

我是ruby新手，也犯了同样的错误。你能告诉我把这个代码放在哪里的确切文件吗？？？@Bongs：错误消息告诉你确切的文件和行。我只需要切换到：gem'gdata_19'，'1.1.5'
