win32 com_error: -2147221008 错误解决

在做多线程的一个例子时，里面用到了win32，结果运行时出错：

Exception in thread Thread-2:
Traceback (most recent call last):
  File "C:\Python25\lib\threading.py", line 486, in __bootstrap_inner
    self.run()

    self.xlApp = win32com.client.Dispatch('Excel.Application')
  File "C:\Python25\Lib\site-packages\win32com\client\__init__.py", line 95, in Dispatch
    dispatch, userName = dynamic._GetGoodDispatchAndUserName(dispatch,userName,clsctx)

    return (_GetGoodDispatch(IDispatch, clsctx), userName)
  File "C:\Python25\Lib\site-packages\win32com\client\dynamic.py", line 84, in _GetGoodDispatch
    IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx, pythoncom.IID_IDispatch)
com_error: (-2147221008, '\xc9\xd0\xce\xb4\xb5\xf7\xd3\xc3 CoInitialize\xa1\xa3', None, None)

 

查了一下，每个进程执行时需要加上一句：pythoncom.CoInitialize()

解决。
