使用 Python 连接到 Google Analytics API

Question

我已尝试关注 this tutorial 以连接到 Google Analytics API。我已按照说明一步一步地进行操作。我的电脑上安装了 Python 2.7。我已经安装了谷歌客户端库。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

我完全迷路了。我查看了其他有相同错误的人here、here 和here，但解决方案不起作用。我有一些编程知识，但与你们中的许多人相比，我是一个菜鸟。

完整代码在这里：

任何帮助或指导将不胜感激。

source repository 最近已更新，Hello Analytics Guides 此后也已更新以使用新代码：

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

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

其中service_account_email 是您从开发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，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其访问的 Google Analytics（分析）数据视图（配置文件）的授权用户。
