    折腾：
    【已解决】Mac中初始化搭建appium的Python的运行环境
    期间，去运行了appium的server，运行python代码，报错：
    发生异常: WebDriverException
Message: An unknown server-side error occurred while processing the command. Original error: Could not find a connected Android device in 20123ms
    报错了，找到内部log是：

    即：
    此处连不上设备。
    所以去：更新设备的信息
    以及插上安卓手机到Mac中
    先确保adb能找到设备：
    ~  adb devices
List of devices attached
orga4pmzee4ts47t    device
    再确保，参数正确：
    【已解决】Mac中如何找到Android手机的appium的参数deviceName
    【总结】
    此处appium启动报错
    Original error: Could not find a connected Android device
    意思是，连不上，找不到设备。
    解决办法：
    • 硬件上
      • 确保安卓设备正常通过USB数据线连接到了Mac中
        • adb devices
          • 可以查看到设备（的udid值）
    • 软件上
      • 参数配置，最核心的是三个
        • platformName：Android
          • 安卓平台
        • udid：安卓设备的序列号，设备唯一编号
          • 可以通过 adb devices 找到
            • 比如：
              • # adb devices
                • List of devices attached
                • orga4pmzee4ts47t    device
            • 中的 orga4pmzee4ts47t
        • deviceName：随便填个值（当然最好是见名知意用户看得懂的值）
          • 比如
            • “deviceName”: “crifan Redmi10X”,
    此处完整的Capability的设置：
    from appium import webdriver

server = 'http://localhost:4723/wd/hub’

Android_Redmi10X_DeviceName = "crifan Redmi10X"
Android_Redmi10X_UDID = “orga4pmzee4ts47t"

    desired_caps = {
        # 如果换手机，需要改 deviceName、udid
        "platformName": "Android",
        "deviceName": Android_Redmi10X_DeviceName,
        "udid": Android_Redmi10X_UDID,
        "appPackage": "com.tencent.mm",
        "appActivity": ".ui.LauncherUI",
        "noReset": True
    }

    desired_caps['chromeOptions'] = {'androidProcess': 'com.tencent.mm:tools'}
    desired_caps['noReset'] = True

    driver = webdriver.Remote(server, desired_caps)
    具体参数解释，详见官网
    Desired Capabilities – Appium
