在用脚本启动 app 时，
console 打出的错误是：

selenium.common.exceptions.WebDriverException: Message: An unknown server-side error occurred while processing the command. Original error: Error executing adbExec. Original error: Command '/usr/local/android-sdk-macosx/platform-tools/adb -P xxxxx -s xxxxxxx shell ls /data/local/tmp/0001183aa4c4852a5fe987466c77d407.apk' exited with code 1{"stdout":"","stderr":"ls: /data/local/tmp/0001183aa4c4852a5fe987466c77d407.apk: No such file or directory\n","code":1}

appium 详细日志：
