我一直在使用下面的代码片段来启动与旧的“ selenium-webdriver” v3.6.0的会话，并收到上述错误：

6月23日更新。

if Capybara.default_driver == :selenium
    Capybara.register_driver :selenium do |app|
        # In the block, we build up an `options` hash to pass to
        #   Capybara::Selenium::Driver.new(app, options)
        # which in turn calls
        #   Selenium::WebDriver.for(options[:browser], options)

        browser = Configuration.fetch('browser.type', :firefox) 
        options = {
            browser: browser, # chrome
        }

        if Configuration.fetch('options.webdriver.use_hub', false)
            {...}
        elsif browser == :firefox
            {...}
        elsif browser == :chrome
            chrome_logpath = "../chromedriver.log"
            options[:service] = ::Selenium::WebDriver::Service.chrome(
                args: {
                    verbose: true,
                    log_path: chrome_logpath,
                }
            )
            chrome_options = Selenium::WebDriver::Chrome::Options.new
            chrome_options.add_argument("user-agent='QA Test'")
            chrome_options.add_option('w3c',false)
            options[:options] = chrome_options
        end
    Capybara::Selenium::Driver.new(app, options)
    end
end

将该gem提升至v3.142.0之后，我得到了该错误。追溯到https://github.com/SeleniumHQ/selenium/blob/master/rb/CHANGES中的Selenium Webdriver Changelog，然后发现以下描述，这可能会破坏当前代码 3.141.592（2019-04-18）

Chrome: 
Added support for instantiating service class directly and moved all driver executable configuration there (command-line arguments, port, etc.)
Passing driver_opts, driver_path and port to driver initializer is now deprecated 
so use Selenium::WebDriver::Service.chrome instead, 
which allows to customize executable behavior in similar way.
 Once initialized, this object can be passed as :service keyword 
during driver initialization. 
* Deprecated Chrome.driver_path= in favor of Service::Chrome.driver_path=

谷歌搜索了一段时间，我发现了一些结果和解决方法，例如使用“ webdriver” gem，但是我不太喜欢它。

所以想知道我是否可以更改上面的代码片段以使其与3.142.0及更高版本的selenium-webdriver相适应？我目前正在使用Capybara v3.18.0。

谢谢大家

这不是错误，而是弃用警告。告诉您在selenium-webdriver v4.0发布之前，您需要更改代码。如果您觉得必须今天更新代码，则类似

elsif browser == :chrome

  options[:service] = ::Selenium::WebDriver::Service.chrome(
    args: {
      verbose: true,
      log_path: "../chromedriver.log",
    }
  )

  chrome_options = Selenium::WebDriver::Chrome::Options.new

  # add user agent to that class options
  chrome_options.add_argument("user-agent='QA Test'")
  options[:options] = chrome_options
end

您显示的其他内容

Screenshot error, but continue to execute.
wrong number of arguments (given 0, expected 1)

有所不同，并非来自您显示的任何代码。

：driver_opts已弃用。将：service与Selenium :: WebDriver :: Service实例结合使用
