使用Python连接到Google Analytics API

Question

我试图按照this tutorial连接到Google AnalyticsAPI。我一直按照说明进行操作。我的电脑上安装了Python 2.7。我已经安装了Google客户端库。当我运行该程序，我得到以下错误在终端：

Traceback (most recent call last): 
    File "HelloAnalytics.py", line 6, in <module> 
    from oauth2client.client import SignedJwtAssertionCredential 
ImportError: cannot import name SignedJwtAssertionCredentials 

6号线，它指的是：

from oauth2client.client import SignedJwtAssertionCredentials 

我是在一个完整的丢失。我查看了其他曾发生过相同错误的人，here,here和here，但解决方案无效。我有一些编程知识，但与你们许多人相比，我是一个小菜鸟。

完整的代码是在这里：

的source repository最近进行了更新，并Hello Analytics Guides以来也进行了更新，以使用新代码：

from apiclient.discovery import build 
from oauth2client.service_account import ServiceAccountCredentials 

... 
credentials = ServiceAccountCredentials.from_p12_keyfile(
    service_account_email, key_file_location, scopes=scope) 

哪里service_account_email是你从开发者控制台获取的服务帐户的电子邮件地址，并且key_file_locaiton是/the/path/to/key.p12，而scopes是您需要授予服务帐户的scopes。

请记住将服务帐户电子邮件地址添加为您希望访问的Google Analytics数据视图（个人资料）的授权用户。
