MonkeyRunner_no codec search functions registered: can't find encoding

#-*- coding:utf-8 -*-
import sys
from com.android.monkeyrunner import MonkeyRunner,MonkeyDevice,MonkeyImage
device = MonkeyRunner.waitForConnection()
devWidth = int(device.getProperty('display.width'))

devHeight = int(device.getProperty('display.height'))

或者代码如下：

import sys
from com.android.monkeyrunner import MonkeyRunner,MonkeyDevice,MonkeyImage
device = MonkeyRunner.waitForConnection()
devWidth = device.getProperty('display.width')
devHeight = device.getProperty('display.height')
print devWidth,devHeight

出现错误如下：

经过查看发现是编码的错误，于是把这一行#-*- coding:utf-8 -*-去掉，重新运行，就Ok了。
