Python、comtypes和ArcObjects:创建Apport对象时出错
我正在Python 2.6.5和ArcGIS 10 SP1下试验Python、comtypes和ArcObjects:创建Apport对象时出错,python,arcobjects,comtypes,Python,Arcobjects,Comtypes,我正在Python 2.6.5和ArcGIS 10 SP1下试验comtypes和ArcObjects。我使用纯Python方法包装中描述的ArcObjects OLB，但在comtypes.CoCreateInstance方法中得到一个错误 以下是我正在运行的代码： def WrapModules(): #force wrapping of all ArcObjects libraries (OLBs) import os import comtypes.client
