python - 导入错误 : cannot import name SignedJwtAssertionCredentials

Question

我正在尝试使用此代码通过 Python 客户端访问 google 应用程序以获得授权(显然已编辑私有(private)信息):

import gflags
import httplib2

from apiclient.discovery import build
from oauth2client.file import Storage
from oauth2client.client import SignedJwtAssertionCredentials
from oauth2client.tools import run

f = open('privatekey.p12', 'rb')
key = f.read()
f.close()
credentials = SignedJwtAssertionCredentials(
    service_account_name='name@developer.gserviceaccount.com',
    private_key=key,
    scope = 'https://www.googleapis.com/auth/calendar')
http = httplib2.Http()
http = credentials.authorize(http)
service = build(serviceName='calendar', version='v3', http=http)

但我收到此错误:

ImportError: cannot import name SignedJwtAssertionCredentials

我已经安装了 Google v3 API Python 客户端以及 OAuth2；我似乎对这些模块没有任何其他问题，尽管我没有太多使用它们。有谁知道发生了什么？

我今天遇到了这个问题，不得不从 oauth2client 2.0 版回滚到 1.5.2 版:

pip install oauth2client==1.5.2
