我正在尝试将 jinja2 与 GAE python 一起使用。每当我编辑 app.yaml 以添加

-name: jinja2
 version:latest

并尝试运行应用程序出现错误。但是，当我将其取出时，错误消失了。这是错误

     File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\yaml_listener.py", line 226, in Parse
    self._HandleEvents(self._GenerateEventParameters(stream, loader_class))
  File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\yaml_listener.py", line 172, in _HandleEvents
    for event in events:
  File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\yaml_listener.py", line 212, in _GenerateEventParameters
    raise yaml_errors.EventListenerYAMLError(e)
google.appengine.api.yaml_errors.EventListenerYAMLError: mapping values are not allowed here
  in "C:\Users\Acer Customer\Desktop\udacity\jonponblog\app.yaml", line 19, column 10
2014-01-15 15:53:01 (Process exited with code 1)

这是 app.yaml

    application: jonponblog
version: 1
runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /favicon\.ico
  static_files: favicon.ico
  upload: favicon\.ico

- url: .*
  script: main.app

libraries:
- name: webapp2
  version: "2.5.2"
- name:jinja2
  version: latest
