Appium: adb server version (31) doesn't match this client (36)

Appium: adb server version (31) doesn't match this client (36)

运行Appium脚本时程序报错（adb server version (31) doesn't match this client (36); killing..." shell pm packages ... with code 1{"stdout":"","stderr":"error: device 'adb server version (31) doesn't match this client (36); killing...' not found\n","code":1}），网上找了半天也没有解决，最终通过删掉/Users/my_user_name/Library/Android/中的sdk文件，然后再将自己Android sdk路径中的sdk复制到/Users/my_user_name/Library/Android/中，问题完美解决。

更新了sdk之后又出现了相同的问题（[AndroidDriver] Using device: adb server version (31) doesn't match this client (39); killing...），通过相同的方法，顺利解决。
