在python中使用COM dll？

我需要在我的python项目中使用COM dll（由CSharp制造）。我尝试遵循此示例，在脚本语言中使用COM对象-第2部分（Python），但没有成功。

我的python代码是：

import sys

# for TkInter GUI support
from Tkinter import *
import tkMessageBox
import tkColorChooser

# for COM support
import comtypes.client as cc
import comtypes

# Load the typelibrary registered with the Windows registry
tlb_id = comtypes.GUID("{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}")
cc.GetModule((tlb_id, 1, 0))

当我运行python类时，会发生此错误：

> Traceback (most recent call last):   File "C:\Program Files
> (x86)\JetBrains\PyCharm 129.696\helpers\pydev\pydevd.py", line 1481,
> in <module>
>     debugger.run(setup['file'], None, None)   File "C:\Program Files (x86)\JetBrains\PyCharm 129.696\helpers\pydev\pydevd.py", line 1124,

>     cc.GetModule((tlb_id, 1, 0))   File "C:\Python27\lib\site-packages\comtypes-1.1.0-py2.7.egg\comtypes\client\_generate.py",

>     tlib = comtypes.typeinfo.LoadRegTypeLib(comtypes.GUID(tlib[0]), *tlib[1:])   File "C:\Python27\lib\site-packages\comtypes-1.1.0-py2.7.egg\comtypes\typeinfo.py",
> line 473, in LoadRegTypeLib

> 945, in GetResult WindowsError: [Error -2147319779] Library not registered

错误行：

cc.GetModule((tlb_id, 1, 0))

在我的CSharp项目中，我的COM dll中包含以下代码：

界面

[InterfaceType(ComInterfaceType.InterfaceIsDual), Guid("YYYYYYYY-YYYY-YYYY-YYYY-YYYYYYYYYYYY")]
public interface ITestCOM
{
    string say_hello();
}

班级

[ClassInterface(ClassInterfaceType.None), Guid("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX")]
public class TestCOM : ITestCOM
{
    public string say_hello()
    {
        return "hello world!";
    }
}

上面的COM项目已在其他应用程序中使用，并且工作正常。我的问题仅在python中。

及时：我的COM dll已在Windows注册表中注册

有帮助吗？
