python - 谷歌应用引擎 'No module named pwd'

Question

我能够很好地运行我的 Google App Engine 项目(我正在使用 Python Flask 开发网络应用程序)，但是当我将系统从 Ubuntu 12.04 升级到 14.04 时。 App Engine 项目在本地系统上变得无响应，但它在生产环境中运行良好。我还保持我的项目更新，将我的源代码放在 github 上，所以我删除了所有内容并再次从我的 github 帐户克隆了一个新的存储库。但是当我运行这个项目时，它给了我以下错误，如果之前有人遇到过这个错误，请帮助我。

我使用这个命令来运行我的项目

$ dev_appserver.py src/

并在终端输出这个错误

如果有人解决了这个问题，请帮我解决以下问题。

Answer 1

在 google_appengine/google/appengine/tools/devappserver2/python/sandbox.py 中有 _WHITE_LIST_C_MODULES 列表，并添加 'pwd'它对我有用。

Google 实际上是在沙盒中运行。由于在生产环境中没有问题，较旧的 GAE SDK 将支持 pwd 导入，但他们即将删除它。
