python - Google API和cx_Freeze无法正常工作

我已经制作了一个python程序，可以将文件上传到google drive。.py文件工作正常，没有任何错误。
但是，由于我将为没有安装python的人分发它，所以我必须将程序和资源转换为.exe。我已经用cxúu Freeze做了这个我以前用过，而且一直有效。
但现在，google drive api似乎在运行.exe时导致了错误。下面是它给出的错误：

在用户输入授权代码后，它会给出此错误。
经过一些调试，我发现导致这个问题的线路是
credentials = flow.step2_exchange(code)
下面是一段代码：

flow = OAuth2WebServerFlow(CLIENT_ID, CLIENT_SECRET, OAUTH_SCOPE, REDIRECT_URI)
authorize_url = flow.step1_get_authorize_url()
webbrowser.open(authorize_url)
code = raw_input('Enter verification code: ').strip()
credentials = flow.step2_exchange(code)
http = httplib2.Http()
http = credentials.authorize(http)
drive_service = build('drive', 'v2', http=http)

CLIENT_ID、CLIENT_SECRET、OAUTH_SCOPE和REDIRECT_URI都配置正确。
那么，这里有什么问题？
如果需要查看更多代码，请提问，我将更新此问题。

最佳答案

似乎找不到您的SSL证书这是可以理解的，因为httplib2从文件系统加载它们，而没有任何东西告诉cx_u freeze将它们放入捆绑包中。
