Question

我尝试关注this tutorial以连接到Google AnalyticsAPI。我一步一步地按照说明进行操作。我的计算机上安装了Python 2.7。我已经安装了Google客户端库。当我运行程序时，我在终端中收到以下错误：

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

它所指的第6行是：

from oauth2client.client import SignedJwtAssertionCredentials

我完全迷失了。我查看了其他具有相同错误的人，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，我是一个菜鸟。

完整的代码在这里：

source repository最近更新了，Hello Analytics Guides也已更新，以便使用新代码：

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

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

其中service_account_email是您从开发者控制台获得的服务帐户的电子邮件地址，key_file_locaiton是/the/path/to/key.p12，而scopes是scopes你需要授予服务帐户。

请务必将服务帐户电子邮件地址添加为您希望其有权访问的Google Analytics（分析）视图（个人资料）的授权用户。
