appium安装完成后运行和执行python脚本的错误合集

 

1、第一个错误如下：

main.js: error: argument "--app": Expected one argument. null

 

这个一般是appium服务端安装的时候路径里面的目录名包含了空格，比如默认安装的目录为“Program Files (x86)”’，中间带有空格。

建议在安装的时候直接安装在根目录下，名称为appium即可，如“C:\appium”

 

 

2、第二个错误如下：

info: [debug] Cleaning up appium session
> error: Failed to start an Appium session, err was: Error: Activity used to start app doesn't exist or cannot be launched! Make sure it exists and is a launchable activity
> info: [debug] Error: Activity used to start app doesn't exist or cannot be launched! Make sure it exists and is a launchable activity
> at [object Object].<anonymous> (D:\Appium\node_modules\appium\node_modules\appium-adb\lib\adb.js:1146:21)
> at [object Object].<anonymous> (D:\Appium\node_modules\appium\node_modules\appium-adb\lib\adb.js:180:9)

> at Socket.<anonymous> (child_process.js:1184:11)
> at Socket.emit (events.js:107:17)
> at Pipe.close (net.js:484:11)

 

这是由于设置的appActivity不对造成的，需要根据实际情况填写

 

 

3、第三个错误如下：

执行python脚本报错：selenium.common.exceptions.SessionNotCreatedException: Message: A new session could not be created. (Original error: An unknown server-side error occurred while processing the command. (Original error: unknown error: Device 621QECQ23DKQP is not online
  (Driver info: chromedriver=2.18.343845 (73dd713ba7fbfb73cbb514e62641d8c96a94682a),platform=Windows NT 6.1 SP1 x86_64)))

解决方法一：增加一个参数appWaitActivity，把后启动的activity放到这里，如百度app：

解决方法二：勾选appium中的参数Override Existing Session
