使用Appium安装uiautomator2驱动程序时出错

我对appium很陌生，我尝试将uiautomator2驱动程序安装到最新的appium 2.0.0-beta版本。41通过命令 appium驱动程序安装uiautomator2

我总是得到这样的输出：文章源自玩技e族-https://www.playezu.com/193088.html

所以这个错误可能与babel试图传输lib/appium有关。js文件？文章源自玩技e族-https://www.playezu.com/193088.html

我已经通过安装了babel pm安装babel cli babel core--保存开发文章源自玩技e族-https://www.playezu.com/193088.html
