使用Python2.7在GAE上运行web2py作为WSGI应用程序

Question

如何设置Web2Py [Version 1.99.4 (2011-12-14 14:46:14) stable]在GAE上使用Python2.7.2作为WSGI应用程序运行？

目前，我的app.yaml文件如下所示：

#  For Google App Engine deployment, copy this file to app.yaml
#  and edit as required
#  See http://code.google.com/appengine/docs/python/config/appconfig.html
#  and http://web2py.com/book/default/chapter/11?search=app.yaml

application: my-app-name
version: 1
api_version: 1

# use this line for Python 2.5
#
# runtime: python

# use these lines for Python 2.7
# upload app with: appcfg.py update web2py (where 'web2py' is web2py's root directory)

runtime: python27
threadsafe: true
# true for WSGI & concurrent requests (Python 2.7 only)

default_expiration: "24h"   
# for static files

handlers:

- url: /(?P<a>.+?)/static/(?P<b>.+)
  static_files: applications/\1/static/\2
  upload: applications/(.+?)/static/(.+)
  secure: optional

- url: /favicon.ico
  static_files: applications/welcome/static/favicon.ico
  upload: applications/welcome/static/favicon.ico

- url: /robots.txt
  static_files: applications/welcome/static/robots.txt
  upload: applications/welcome/static/robots.txt

- url: .*
  script: gaehandler.py         
  # CGI
#  script: gaehandler.wsgiapp    # WSGI (Python 2.7 only)
  secure: optional

admin_console:
  pages:
  - name: Appstats
    url: /_ah/stats

builtins:

- datastore_admin: on
- appstats: on
- admin_redirect: on
- deferred: on

但是在尝试使用AppEngine SDK for Python (v1.6.3)加载应用程序时出现以下错误：

2012-03-10 12:37:01 Running command: "[u'C:\\Python27\\pythonw.exe', 'C:\\Program Files\\Google\\google_appengine\\dev_appserver.py', '--admin_console_server=', '--port=8088', u'E:\\Programming\\Python\\web2py']"
WARNING  2012-03-10 07:07:18,851 rdbms_mysqldb.py:74] The rdbms API is not available because the MySQLdb library could not be loaded.
ERROR    2012-03-10 07:07:20,483 dev_appserver_main.py:581] Fatal error when loading application configuration:

  in "E:\Programming\Python\web2py\app.yaml", line 90, column 1
2012-03-10 12:37:20 (Process exited with code 1)

另外，对于threadsafe WSGI应用程序，还有什么我应该知道的，因为我是新手吗？ 我是否需要对我的应用进行任何更改才能将其作为一个应用程序运行？

注释掉gaehandler.py行并取消注释gaehandler.wsgiapp行。
