我正在尝试在本地测试 gae-boilerplate，但是当我尝试创建一个新帐户时出现以下错误。
奇怪的是，如果我打开 python 解释器并输入“import pwd”，它就会工作。

最佳答案
我认为此问题是由 AppEngine SDK 更新引入的。我目前使用的是 1.8.6 版。 gae 样板 README声明它已经“使用 SDK 版本 1.8.1 进行了测试”
我能够通过运行 old_dev_appserver.py <application root> 在本地运行它old_dev_appserver.py由SDK提供，与dev_appserver.py在同一目录下。
根据我得到的回溯，它看起来像文件 boilerplate/external/requests/utils.py imports netrc 导入 pwd。 较新版本的 SDK 不允许您在其沙盒模式下导入 pwd 模块。
关于python - "ImportError: No module named pwd"但它存在，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18819604/
