python：IOError：[Errno 13]權限被拒絕。 當我嘗試使用google-analytics-api示例代碼時

Question

我正在嘗試從google-analytics-api獲取數據，我運行了示例代碼：HelloAnalytics.py（ https://developers.google.com/analytics/devguides/reporting/core/v3/quickstart/service-py ），但是有一些錯誤：IOError：[Errno 13]我已將服務帳戶電子郵件地址添加到我正在使用mac os的GA帳戶中。

詳細錯誤消息：

Answer 1

您正在使用服務帳戶。 您是否授予服務帳戶訪問您的Google Analytics（分析）帳戶的權限？

轉到“管理員”下的Google Analytics（分析）網站，將ACCOUNT級別的服務帳戶電子郵件地址添加到您要為其請求數據的帳戶中。

想法二：

IOError: [Errno 13] Permission denied請檢查您是否對p12文件具有IOError: [Errno 13] Permission denied 。
