10.0以后的系统使用下面的方法来安装。

Some time ,the default

source of gem,https://rubygems.org/, can't be accessed.

It should be removed by

command :gem sources -rhttps://rubygems.org/

And then add new source :gem sources -ahttp://ruby.taobao.org/

Update the cache:gem sources -u

You can check

souces: gem sources

Finally , you can install
