我制作了一个能够将文件上传到 Google Drive 的 Python 程序。.py 文件完美运行，不会出现任何错误。
但是因为我要为没有安装 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 cx_Freeze 做到了这一点。我以前用过它，它一直有效。
但是现在，运行 .exe 时，Google Drive API 似乎会导致错误。以下是它给出的错误：

用户输入授权码后会出现此错误。
经过一番调试，我发现导致这个问题的行是
credentials = flow.step2_exchange(code)
这是代码片段：
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，这可能是什么问题？
如果您需要查看更多代码，请询问，我将更新此问题。
