我在 Win 8 x64，Python 2.7
我遵循的步骤：
- 下载，安装python。
- 已下载、安装 Google App Engine Launcher。
helloworld-kg在应用引擎站点上创建了具有名称的新应用程序。- 在 Launcher 中，文件 > 创建新应用程序 > 输入应用程序的名称并浏览到目录。
- 点击运行，等待灯变绿。
- 单击浏览器。得到一个空白页
localhost:8080
这是启动器的日志：

我的app.yaml文件内容：
application: helloworld-kg
version: 1
runtime: python27
api_version: 1
threadsafe: true
handlers:
- url: /.*
script: helloworld-kg.app
和helloworld-kg.py文件内容：
import webapp2
class MainPage(webapp2.RequestHandler):
def get(self):
self.response.headers['Content-Type'] = 'text/plain'
self.response.write('Hello, webapp2 World!')
app = webapp2.WSGIApplication([('/', MainPage)],
debug=True)
我是 Python 和 GAE 的新手。这是针对 Udacity 的 CS 253 课程的。
可能的解决方案？
