“ImportError：没有名为pwd的模块”，但它存在
我试图在本地测试gae-boilerplate，但是当我尝试创建新帐户时，出现以下错误。
奇怪的是，如果我打开python解释器并键入“导入密码”它的作品。

我相信这个问题是由AppEngine SDK更新引入的。 我目前正在使用1.8.6版本。 gae-boilerplate自述文件指出它已经“使用SDK 1.8.1测试”
我能够通过运行old_dev_appserver.py <application root>来本地运行它。old_dev_appserver.py由SDK提供，并位于与dev_appserver.py相同的目录中。
基于我得到的回溯，它看起来像文件boilerplate / external / requests / utils.py导入了导入pwd的netrc。 较新版本的SDK不允许您在其沙箱模式下导入pwd模块。
你可能用easy_install安装了pycrypto。 如果你用pip重新安装它，一切都应该工作：
pip uninstall pycrypto
pip install pycrypto
请注意， pip uninstall即使与easy_install一起安装，也可以运行。 你也可能需要使用sudo 。
如果您没有pip ，请像这样安装它：
sudo easy_install pip
