刚开始为 App Engine (Python) 设置。当我在上面运行任何应用程序时，http://localhost:8080我得到了这个：

<type 'exceptions.RuntimeError'>    Python 2.5.2: E:\Python25\pythonw.exe
Tue Dec 25 13:40:46 2012

A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred.

据我了解，这只是 Python 安装的问题，因为应用程序在部署时运行良好。

我已经安装了 Python 2.5.2。

到底发生了什么？

我从日志中假设原因是您正在尝试使用 python25 运行应用程序引擎。

选项 1：编辑您的 app.yaml 并将 python25 放在您的运行时。其余的你可以保留它，因为你已经设置好了

application: bismillah
version: 1
runtime: python25
api_version: 1

选项 2：安装 python 2.6 或 python 2.7 并将其设为您的系统默认值，或者仅将其用于谷歌应用引擎
