py2exe 运行编译的exe时 ctypes dll 加载错误，但使用解释器时正常

Question

我正在使用py2exe来编译一个exe文件。

当我在命令行(cmd)中像这样测试代码时：

C:\wdir\mvl-tryton-client\tryton-3.2.3\bin>python tryton

一切都运行得很好。

但是当我在执行生成的安装程序后运行它时，我得到了：

Error DLL load failed: The specified procedure could not be found.

File "tryton\common\common.pyc", line 1341, in process
File "tryton\gui\main.pyc", line 878, in _set_preferences

File "ctypes\__init__.pyc", line 10, in <module>
File "_ctypes.pyc", line 12, in <module>
File "_ctypes.pyc", line 10, in __load

我猜可能是setup.py中缺少一些配置，或者是缺少指向ctypes库的路径，但我在文档中找不到具体的信息。

任何帮助或提示都非常感谢。谢谢。

编辑：这是_ctypes.py。我尝试打印name和路径变量。但是当我从命令行运行exe时，没有任何输出。

def __load():
    import imp, os, sys
    try:
        dirname = os.path.dirname(__loader__.archive)
    except NameError:
        dirname = sys.prefix
    path = os.path.join(dirname, '_ctypes.pyd')
    #print "py2exe extension module", __name__, "->", path
    mod = imp.load_dynamic(__name__, path)
##    mod.frozen = 1
__load()
del __load

谢谢大家的评论。我解决这个问题的方法是，在setup.py文件的包含部分添加了ctypes和_ctypes这两个包，像这样：

args['options'] = {
    'py2exe': {
        'optimize': 0,
        'bundle_files': 3,  # don't bundle because gtk doesn't support it
        'packages': [
            'encodings',
            'gtk',
            'pytz',
            'atk',
            'pango',
            'pangocairo',
            'gio',
            'ctypes',
            '_ctypes'
        ],
        'dll_excludes': [ "mswsock.dll", "powrprof.dll" ]
    }
}
