当我尝试在
ruby 2.0.0-p0中安装vagrant gem时,我遇到了以下错误：
~ ruby -v ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-linux] ~ gem -v 2.0.0.rc.2 ~ gem list json *** LOCAL GEMS *** json (1.7.7) ~ gem install vagrant Building native extensions.

我想,它在构建gem并获得上述错误时使用/home/user_name/.rvm/gems/ruby-2.0.0-p0/gems/中的json-1.5.5.
我尝试重新安装最新的json-1.7.7 gem,但仍然无法安装.
解决方法
使用：gem update –system更新你的rubygems
以下是解决此问题的提交：https://github.com/rubygems/rubygems/commit/1ca11d00833bbca33215ff581303d1fee8f2d1ef
