python - 仅在某些文件中“导入错误没有名为 httplib2 的模块”

Question

当我在 quickStart.py 中导入 httplib2 并使用终端运行它时它可以工作。

现在我将 quickStart 导入另一个文件 main.py（Google 应用引擎 web 应用程序 python 文件）并尝试通过 localhost 加载页面，它显示“导入错误没有名为 httplib2 的模块”，而这两个文件位于同一目录中。 它显示以下错误：-

Google App Engine 要求将任何第 3 方模块包含在应用程序源代码树中，以便将其部署到 App Engine。这意味着site-packages 中的项目不会被导入到在开发 SDK 下运行的应用程序中，您将看到与您遇到的类似的错误。

Here are the docs 了解如何包含 httplib2 等库。

简而言之，您需要pip install -t some_dir <libname>，然后将some_dir 添加到appengine_config.py 内的应用程序路径中
