我正在尝试在 gae 上使用 pytz 并找到 gaepytz。但是，导入时出现导入错误，我认为这是因为我没有将原始 pytz 和 gaepytz 正确并排放置在我的应用程序目录中。（假设我需要！）

./appdir/pytz [原始​​ pytz 文件夹，包括 zoneinfo 子目录]

./appdir/gaepytz

在中的一个foo.py文件中appdir，我有：

从gaepytz.gae import pytz

导入 zipfile 时出现错误gae.py，这反过来又无法导入 _io 模块。

ImportError：没有名为 _io 的模块

我错过了什么？谢谢

在进行更多实验时，我发现即使没有 gaepytz ie 也会出现此错误。在 helloworld 应用程序中导入 zipfile 会出现以下错误：

如果您尝试使用 Python 2.7 运行 dev_appserver，则会出现此错误，而 Python 2.7 目前无法运行。请改用 Python 2.5。如果您针对 Python 2.7 运行时进行开发，请记住 dev_appserver 尚不支持它，您必须进行部署才能测试您的代码。
