ImportError:没有名为oauth2client的模块

Question

我正在遵循Google登录Android文档(https://developers.google.com/identity/sign-in/android/backend-auth)中的说明，并试图在我的Python代码中实现令牌验证。

我正在开发本地主机。由于某些原因，当我尝试将这个导入from oauth2client import client, crypt导入我的Google后端时，我得到了这个错误：

ImportError: No module named oauth2client.client`

我使用sudo安装了oauth2 -升级google (https://developers.google.com/api-client-library/python/start/installation)。安装日志显示：

我看到有人给出了答案，但我不知道如何实现这里描述的符号链接：Google app engine(python) ImportError: No module named oauth2 in google app engine

我认为这与路径有关，但我不知道如何设置它，以便在全球范围内安装oauth2client。我正在VM上运行Ubuntu14.04LTS。

任何帮助都将不胜感激。

Answer 1

我刚刚从Google https://cloud.google.com/appengine/docs/python/tools/libraries27#vendoring中了解到了将第三方软件包安装到应用程序的文档。

按照说明，我在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文件中，我输入了以下内容：

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

然后，在我的终端上，在我的项目文件夹中，我输入了sudo pip install -t lib google-api-python-client。

这起作用了！导入不再抛出错误。
