我的 GF 正在尝试学习 Udacity 的 Web 开发课程,但她遇到了问题。而我解决不了。刚开始必须创建一个在 AppEngine 上运行的“hello world”Python 脚本。
所以,文件:
应用程序.yaml:
application: focus-invention-298
version: 1
runtime: python27
api_version: 1
threadsafe: true
handlers:
- url: /.*
script: helloworld.app
你好世界.py:
# -*- coding: utf8 -*-
import webapp2
class MainPage(webapp2.RequestHandler):
def get(self):
self.response.headers['Content-Type'] = 'text/plain'
self.response.write('Hello, Udacity!')
application = webapp2.WSGIApplication([('/', MainPage)], debug=True)
但是,当我运行应用程序(通过 GUI 启动器或使用 dev_appserver.py)并在浏览器中打开应用程序时,我收到此错误(在控制台中):
Traceback (most recent call last):

我们在 OSX 10.8.4 上,当我在终端中运行 python 时,它告诉我我安装了 2.7.2 版本。AppEngine 启动器(或 SDK)版本为 1.8.2。
任何人?我现在尝试了很多事情都没有成功,以至于我真的不知道该怎么做了(我不是 python 开发人员),我真的想让这件事发挥作用,这样我的 GF 就可以继续学习了 :)
