获取二维码时出现 FileNotFoundError: [Errno 2] No such file or directory: 'xdg-open'

大大您好，我今天在自己的服务器上尝试配置wxpy，做到第二步获取二维码时报错，
机器是ubuntu14.04 root用户登陆
屏幕输出如下

>>> robot = Robot()
Getting uuid of QR code.

请问是我遗漏了什么步骤吗

在服务器上运行，可以使用终端二维码，请注意下面文档中 console_qr 参数说明
http://wxpy.readthedocs.io/zh/latest/api/robot.html?highlight=console_qr#wxpy.Robot

试试

robot = Robot(console_qr=True)

如果捕获这个异常，跳过继续执行，二维码可以保存成图片。否则程序异常就终止执行了。
