Question

当我运行以下代码时：

require "selenium-webdriver"
require 'rubygems'
require 'watir-webdriver'

b = Watir::Browser.new :phantomjs
b.goto 'http://www.google.com'
puts b.title
b.close

显示以下错误：

phantomjs未连接。我也试过Firefox，结果是一样的。

Answer 1

根据“无法连接到服务器 127.0.0.1 ”，您似乎无法到达本地计算机外部127.0.0.1是您的环回地址（对于您的计算机）而且我有看到这个问题在过去出现防火墙时出现了。如果您所在的公司需要通过防火墙路由流量，我建议您查看是否有任何流量试图通过您的计算机进行流量传输。如果您不在需要防火墙的公司，那么我建议删除防火墙/代理进行测试。

Answer 2

看起来你是PROXY的幕后推手。在启动服务器之前添加以下代码段：

ENV['HTTP_PROXY'] = ENV['http_proxy'] = nil
b = Watir::Browser.new :phantomjs

为什么Selenium Web Driver说服务不可用？
