Question

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

我想，在构建gem并获得上述错误时，使用来自/home/user_name/.rvm/gems/ruby-2.0.0-p0/gems/的 json-1.5.5

我尝试重新安装最新的 json-1.7.7 gem，但仍无法安装。
