Appium Watir Chromedriver处理命令时发生未知的服务器端错误

Question

我的项目有以下代码：

功能/env.rb

require 'rubygems'
require 'rspec'
require 'watir'
require 'webdrivers'
require 'yaml'
require 'fileutils'
require './features/Util/Tools.rb'
require 'json'
require 'watir-scroll'
require "mini_magick"
require 'watir-screenshot-stitch'
require 'appium_lib'
require 'selenium-webdriver'

    server_url = 'http://localhost:4723/wd/hub/'

    capabilities =
    {
    platformName: 'Android',
    platformVersion: '7.0',
    deviceName: 'Android Emulator',
    browserName: 'Chrome'
    }

    $navegador = "chrome_dev_mobile"

    $appium_driver = Selenium::WebDriver.for(:remote, :desired_capabilities => capabilities, :url => server_url)

    $driver Watir::Browser.new $appium_driver

当我运行cucumber功能时，出现以下错误：

And Verificar Portal abierto                   # features/step_definitions/Home/Home_Chile/SD1_Home.rb:16

  features/features/Pruebas_Mobile/CL_Mobile.feature:4:in `And Verificar Portal abierto'

这是里面的代码。/features/pages/Home/Home\u Page/P1\u HomePage.rb:20

def verificar_pagina
      @caja_busqueda.wait_until_present
      if @caja_busqueda.present?
        puts "Portal abierto satisfactoriamente con: " + $navegador
      end
  end

手机浏览器打开我的URL，然后出现此错误。请我尝试一切，我接受建议

我手动设置了appium chromedriver路径，并很好地使用了它。查看appium日志将显示以下详细信息：

Answer 1

（会话信息：chrome=69.0.3497.100)

在这个chromedriver页面上，他们说你应该为Chrome69-71v使用驱动程序2.43。更新webdriver是否解决了您的问题？不过，v2.42还应支持69版。但这里提到了一系列修复，比如：

修正了在元素可见时不等待的问题

当我通过桌面应用程序启动appium时，我也注意到了同样的iShown问题。但对我来说，解决这个问题的方法是手动下载chromedriver，并通过命令提示符启动appium，如本appium页面所述。

appium--chromedriver可执行文件/path/to/my/chromedriver

Answer 2

我这样证明：

require 'watir'
require 'selenium-webdriver'

    server_url = 'http://localhost:4723/wd/hub/'

    capabilities =
    {
    platformName: 'Android',
    platformVersion: '7.0',
    deviceName: 'Android Emulator',
    browserName: 'chrome'
    }


    $driver = Selenium::WebDriver.for(:remote, :desired_capabilities => capabilities, :url => server_url)

    $driver.get "http://www.google.com"

它工作！！！

但是当一个投手

$appium_driver = Selenium::WebDriver.for(:remote, :desired_capabilities => capabilities, :url => server_url)
$driver = Watir::Browser.new $appium_driver

然后在我尝试与定位器交互时显示错误。

我不知道，可能是水、硒和阿皮姆之间的冲突。这是一个遗憾，因为我有一个关于Watir的整个项目，我不能在移动设备上重复使用所有这些代码。

任何建议都可以接受
