Net::ReadTimeout Watir::Browser.new 时出错
Net::ReadTimeout Error when Watir::Browser.new
我正在尝试启动 watir 浏览器，
irb(main):001:0> require 'watir'
=> true
irb(main):002:0> browser = Watir::Browser.new
Watir 打开一个新的 chrome 浏览器，并在搜索栏中输入 data:,。等待 60 秒后，浏览器关闭，我在控制台中收到此错误：

我该如何解决这个问题？
正如您所说，当页面加载超过 60 秒时会发生这种情况，您可以通过以下代码增加页面加载超时
client = Selenium::WebDriver::Remote::Http::Default.new
client.read_timeout = 120 # seconds
driver = Selenium::WebDriver.for :firefox,http_client: client
b=Watir::Browser.new driver
现在您的代码将等待 120 秒以加载由 #click 引起的任何页面加载，并等待通过 goto 方法加载 url。
watir 6.19.0+
从 watir 版本 6.19.0 开始，他们提供了自己的 HTTPClient，因此您可以这样做：
Watir::Browser.new :firefox, http_client: { read_timeout: 120 }
