Python的COM服务器抛出“模块”对象有没有属性“VARIANT”(Python COM ser

下面是用Python实现的COM服务器：

from win32com.server.exception import COMException
import pythoncom
import sys
import os
from string import Template
import logging
import logging.config

class Connector:
    _reg_clsctx_ = pythoncom.CLSCTX_LOCAL_SERVER
    _reg_clsid_ = "{0CE25AEB-1AFA-4DA7-97BD-F93CDBFB376C}"
    _reg_desc_ = "Python Test COM Server"
    _reg_progid_ = "Compy.Connect"
    _public_methods_ = ['Process', 'Status']
    _public_attrs_ = []
    _readonly_attrs_ = []

    def Process(self, what):
        pass

    def Status(self):
        return Template("""
        Current Directory: $dir
        Installed: $script
        PythonPATH: $pyPath
        """).substitute(dir = os.getcwd(),
                        script = os.path.abspath(__file__),
                        pyPath = sys.path)

if __name__ == '__main__':
    import win32com.server.register
    win32com.server.register.UseCommandLine(Connector)

它注册确定。 当它运行它会导致生产的计算机上，但不是在发展框会出现以下情况：

>>> cc = CreateObject("Compy.Connect")
>>> cc.Status()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python26\lib\site-packages\comtypes\client\dynamic.py", line 42, in _
_call__
    return self._obj._comobj.Invoke(self._id, *args)
  File "C:\Python26\lib\site-packages\comtypes\automation.py", line 717, in Invo

raise COMError(hresult, text, details)
_ctypes.COMError: (-2147352567, 'Exception occurred.', (u"Unexpected Python Erro
r: AttributeError: 'module' object has no attribute 'VARIANT'\n", u'Python COM S
erver Internal Error', None, 0L, -2147467259))
>>>

我已经安装了comtypes 0.6.2。 运行的Python 2.6.6

Answer 1:

该VARIANT类是在Pywin32推出打造217试机，它的失败上安装最新版本。
