Ruby Watir-无法建立连接，因为目标计算机主动拒绝了它。-连接（2）以表示；127.0.0.1“；端口9518

我是ruby和watir的新手。我正在尝试运行以下行：

require 'watir-webdriver'
b = Watir::Browser.new :chrome
b.goto 'https://www.google.co.in/'

Chrome已打开，但浏览器无法获取google页面。我得到以下错误：

Errno::ECONNREFUSED: No connection could be made because the target machine actively refused it. - connect(2) for "127.0.0.1" port 9518

我寻找了其他主题和问答，但没有找到明确的答案。

此堆栈链接中已经给出了最好的解释。请检查您的chrome和chromedriver版本是什么？您应该尝试更新到最新版本。@orde我是最新版本的both@dsnraghavendrarao我读了好几遍，从我的理解来看，在这种情况下，调用方法会导致问题。我没有任何方法，只有简单的脚本。确保你已经安装了最新版本的Chrome驱动程序，即2.25，这个问题在我安装了最新版本的Chrome驱动程序后得到了解决。
