只需一个简单的脚本来自动化一个 firefox 浏览器：只需一个简单的脚本来自动化一个 firefox 浏览器：

require 'rubygems'
require 'watir-webdriver'
# Initialize watir firefox browser
$browser = Watir::Browser.new :ff , :profile => 'default'

导致以下我无法弄清楚的错误。是否有 TCP 端口被阻止或其他原因？。顺便说一句，我正在使用我的办公室电脑，代码在我的家用电脑上运行良好。

如果要安装 gems，则必须在 PATH 中设置 http_proxy 环境变量。但这会导致 watir-webdriver 出现上述问题，在删除 http_proxy 变量后它对我有用。然后它使用浏览器中的代理设置。
