Question

我在添加gem源时遇到ResolveTimeout异常。这是什么意思？

以下是gem env：

以下是gem source：

的结果

*** CURRENT SOURCES ***

如你所见，我没有任何消息来源。但是当我尝试添加一个时：

gem sources -a http://mirrors.aliyun.com/rubygems/ -V --debug

我收到一个ResolvTimeout异常：

NOTE:  Debugging mode prints all exceptions even when rescued
Exception `LoadError' at /usr/local/Cellar/ruby/2.2.2/lib/ruby/2.2.0/resolv.rb:168 - LoadError

ResolvEimtout例外是什么意思？

运行gem sources --add https://rubygems.org -V --debug仍有错误：
