使用Python連接到Google Analytics API

Question

我試圖按照this tutorial連接到Google AnalyticsAPI。我一直按照說明進行操作。我的電腦上安裝了Python 2.7。我已經安裝了Google客戶端庫。當我運行該程序，我得到以下錯誤在終端：

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

6號線，它指的是：

from oauth2client.client import SignedJwtAssertionCredentials 

我是在一個完整的丟失。我查看了其他曾發生過相同錯誤的人，here,here和here，但解決方案無效。我有一些編程知識，但與你們許多人相比，我是一個小菜鳥。

完整的代碼是在這裏：

from oauth2client.client import SignedJwtAssertionCredentials

from oauth2client import client

       service_account_email):

任何幫助或方向將不勝感激。

的source repository最近進行了更新，並Hello Analytics Guides以來也進行了更新，以使用新代碼：

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

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

哪裏service_account_email是你從開發者控制檯獲取的服務帳戶的電子郵件地址，並且key_file_locaiton是/the/path/to/key.p12，而scopes是您需要授予服務帳戶的scopes。

請記住將服務帳戶電子郵件地址添加爲您希望訪問的Google Analytics數據視圖（個人資料）的授權用戶。
