我正在使用AppEngine映射器API(mapreduce)并且导致导入问题。这是我的文件结构:

我的app.yaml是:
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
我的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: ""
最后是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)
现在的问题是,虽然我可以加载/ mapreduce页面并且作业可用,但是一旦我尝试启动作业,我就会收到以下错误(在页面上):
ImportError: Could not find 'input_readers' on path 'google.appengine.ext.mapreduce'
这是一个完整的堆栈跟踪:
