我想在windows env中执行monkeyrunner，但我收到错误：
from com.dtmilano.android.viewclient import ViewClient
File "D:\Work\technology\Myeclipse\Android_SDK\windows-x86-20130219\sdk\tools
AndroidViewClient\src\com\dtmilano\android\viewclient.py", line 25, in <module>
if 'monkeyrunner' in sys.executable:
TypeError: 'NoneType' object is not iterable
