ruby - 树莓派上的 ruby​​ 和 selenium-webdriver -> 协议不支持的地址系列 - socket(2) (Errno::EAFNOSUPPORT)

Question

我想在我的 Raspberry Pi 上运行一个 ruby​​ 脚本。我已经通过 rvm 安装了 ruby​​。我确定，我使用的是正确的版本：

$ rvm current
ruby-1.9.3-p194

当我运行我的脚本时，我得到以下信息：

./test.rb 
/home/pi/.rvm/gems/ruby-1.9.3-p194/gems/selenium-webdriver-2.25.0/lib/selenium/webdriver/common/port_prober.rb:25:in `initialize': Address family not supported by protocol - socket(2) (Errno::EAFNOSUPPORT)

from ./test.rb:54:in `each'
from ./test.rb:54:in `<main>'

任何想法，有什么问题？我试过重新启动，这并不能解决问题...
