使用Python（PyMTP）将Android设备安装到系统

Question

我已经编写了一个python代码，将我的android物理设备安装到笔记本电脑上（ubuntu14.04）。在

我提到了这个http://www.anythingbutipod.com/forum/showthread.php?t=32817

$ sudo apt-get install libmtp mtptools mtpfs
#Once all of that is installed, you will need to create a mountpoint for your device.

$ sudo mkdir /media/MyZen
$ sudo chmod 775 /media/MyZen

#Next, plug in your player and mount it:

$ sudo mtpfs -o allow_other /media/MyZen
#Your player should appear on your desktop as a regular drive. Be aware that, depending on the device, access might be slow.

#IMPORTANT: DO NOT DISCONNECT YOUR DEVICE WITHOUT UNMOUNTING IT FIRST!

$ sudo umount /media/MyZen

这是我写的代码：指定文件夹.py

^{pr2}$

当我运行文件时指定文件夹.py，我得到这个错误
