ruby-on-rails – Watir-Webdriver – 协议不支持的地址族 – socket(2)

我一直在使用watir-webdriver / MiniTest框架不到一个月,而且一直都很顺利.然而,每次启动新构建时我需要运行的包包含不到100个单独的测试,这需要花费一个多小时来完成所有这些测试.

这就是我在Centos-6-x86_64上使用Ruby,RVM,Watir,Rails和Firefox设置VPS的原因.这样我就不必在我的笔记本电脑上运行脚本并等待它们完成,然后才能做其他事情.

但是,当我试图测试watir使用irb工作时,我收到以下错误：

Errno::EAFNOSUPPORT: Address family not supported by protocol - socket(2)

测试：

[root@V-9876 ~]# irb

1.9.3p448 :002 > b = Watir::Browser.start 'www.google.com'

我一直在研究这个错误,我发现许多网站声称它是通过禁用ipv6修复的,我做了,我仍然得到这个错误.

不确定这是否有所不同,但我也在这个VPS上安装了NGinX / PHP / MySQL

编辑 – ruby文件发布在下面

require "watir-webdriver"
require 'watir-webdriver'
require 'headless'
headless = Headless.new
headless.start

browser = Watir::Browser.new :ff
browser.goto "http://remove-url-for-this-post.com" 
puts ("Starting SearchValSelectFields")
browser.select_list(:id, "edit-select-sector").select("Finance and Accounting")
sleep (5)
browser.select_list(:id, "edit-select-subsector--3").select("All Sub-sector")
browser.select_list(:id, "edit-select-location").select("Singapore")
browser.button(:value,"Search").click
assert(browser.text.include?("Salary and employment forecast"))
browser.screenshots ('..\screenshots\SearchValSelectFields.png')
browser.select_list(:id, "edit-select-sector").select("Select Sector")
sleep(3)
browser.select_list(:id, "edit-select-subsector--2").select("Select Sub-sector")
sleep(3)
browser.select_list(:id, "edit-select-location").select("Select Location")
sleep(3)
browser.button(:value,"Search").click
assert(browser.text.include?("This field is required"))
browser.close
headless.destroy

有任何想法吗？

工作的人设法解决了这个问题.他说：

They try to connect twice
first to 127.0.0.1 port 7055
then too ::1 port 7055
second one fails
::1 is localhost of IPv6
so you seem to be connecting localhost
and in your server look at /etc/hosts
localhost resolves to the ::1

所以你要做的就是编辑你的/ etc / hosts文件并注释掉:: 1或者你想要删除它
