ImportError：沒有名為oauth2client的模塊

Question

我正在遵循Android的Google登錄文檔（ https://developers.google.com/identity/sign-in/android/backend-auth ）中的說明，並嘗試在我的Python代碼中實施令牌驗證。

我正在本地主機上開發。 出於某種原因，當我嘗試from oauth2client import client, crypt此導入時，收到此錯誤from oauth2client import client, crypt到我的Google App Engine后端，出現以下錯誤：

ImportError: No module named oauth2client.client`

我已經使用sudo pip install --upgrade google-api-python（ https://developers.google.com/api-client-library/python/start/installation ）安裝了oauth2。 安裝日志顯示：

我看到有人提供了答案，但是我不知道如何執行此處描述的符號鏈接： Google App Engine（python）ImportError：Google App Engine中沒有名為oauth2的模塊

我在想這與路徑有關，但是我不知道如何設置它以便全局安裝oauth2client。 我在VM上運行Ubuntu 14.04 LTS。

任何幫助，將不勝感激。

Answer 1

我剛剛從Google App Engine https://cloud.google.com/appengine/docs/python/tools/libraries27#vendoring中找到了此文檔，用於將第三方程序包安裝到該應用程序。

按照說明，我在項目文件夾中創建了一個名為“ lib”的文件夾，並在項目文件夾中也創建了一個名為appengine_config.py的文件。

在appengine_config.py文件中，輸入以下內容：

from google.appengine.ext import vendor
vendor.add('lib')

然后，在終端上的項目文件夾中，我輸入了sudo pip install -t lib google-api-python-client 。

這工作了！ 導入不再引發錯誤。
