Ошибка импорта API AppEngine Mapper

1 голос
/ 28 сентября 2011

РЕДАКТИРОВАТЬ: Я только что попробовал сам appengine, и кажется, что он действительно работает там, так что проблема только с сервером dev.Мне все равно было бы интересно понять, почему это происходит ...

Я использую AppEngine mapper API (mapreduce) и у меня проблема с импортом.Вот моя файловая структура:

Мой app.yaml: 

application: <removed>
version: 1
runtime: python
api_version: 1

builtins:
- datastore_admin: on
- appstats: on

handlers:
- url: /remote_api
  script: $PYTHON_LIB/google/appengine/ext/remote_api/handler.py
  login: admin

- url: /admin
  script: admin/admin.py
  login: admin

- url: /dhandler/.*
  script: dhandler/dhandler.py

- url: /mapreduce(/.*)?
  script: $PYTHON_LIB/google/appengine/ext/mapreduce/main.py
  login: admin

- url: /static
  static_dir: static

- url: /.*
  script: main.py

Мой mapreduce.yaml: 

mapreduce:
- name: insert-domain-mapper
  params:
  - name: done_callback
    value: /dhandler/insert_job_done
  mapper:
    input_reader: google.appengine.ext.mapreduce.input_readers.BlobstoreLineInputReader
    handler: mappers.insert_domain
    params:
    - name: blob_keys
      default: ""

Наконец, mappers.py 

from  google.appengine.ext.mapreduce import operation as op

from data import RegisteredDomain, make_key, clean_domain

def insert_domain((byte_offset, line)):

    domain = line

    # TODO: domain validity check (??)

    # clean domain
    domain = clean_domain(domain)

    # create domain entity
    domain_entity = RegisteredDomain(key_name=make_key(domain))

    # yield put operation
    yield op.db.Put(domain_entity)

Теперь проблема в том, что, хотя я могу загрузить страницу / mapreduce и работа доступна, как только я пытаюсь запустить работу, я получаю следующую ошибку (на странице): 

ImportError: Could not find 'input_readers' on path 'google.appengine.ext.mapreduce'

Вот полная трассировка стека:
