ImportError：没有名为oauth2client的模块

Question

我按照Google登录Android版文档（https://developers.google.com/identity/sign-in/android/backend-auth）中的说明操作，试图在我的Python代码中实现令牌验证。

我正在开发本地主机。出于某种原因，当我尝试这个进口from oauth2client import client, crypt到我的谷歌应用程序引擎的后端我得到这个错误，我得到这个错误：

ImportError: No module named oauth2client.client` 

我已经安装的oauth2使用sudo PIP安装--upgrade谷歌API - python （https://developers.google.com/api-client-library/python/start/installation）。安装日志显示：

我看到有人提供了一个答案，但我不知道如何做到这一点的符号链接此处介绍：该Google app engine(python) ImportError: No module named oauth2 in google app engine

我想这有什么与路径有关，但我不知道如何设置，以便oauth2client在全局安装。我在VM上运行Ubuntu 14.04 LTS。

任何帮助，将不胜感激。

我刚刚从Google App Engine https://cloud.google.com/appengine/docs/python/tools/libraries27#vendoring中发现了此文档，以便将第三方软件包安装到应用程序中。

根据说明，我在我的项目文件夹中创建了一个名为'lib'的文件夹，并在我的项目文件夹中创建了一个名为appengine_config.py的文件。

在appengine_config.py文件，我进入了以下内容：

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

然后，我的终端上，而我的项目文件夹内，我进入sudo pip install -t lib google-api-python-client。

这工作！导入不再抛出错误。
