这是我的导入代码谷歌云数据流无法导入“google.cloud.datastore”
from __future__ import absolute_import
import datetime
import json
import logging
import re
import apache_beam as beam
from apache_beam import combiners
from apache_beam.io.gcp.bigquery import parse_table_schema_from_json
from apache_beam.io.gcp.datastore.v1.datastoreio import ReadFromDatastore
from apache_beam.pvalue import AsDict
from apache_beam.pvalue import AsSingleton
from apache_beam.options.pipeline_options import PipelineOptions
from google.cloud.proto.datastore.v1 import query_pb2
from google.cloud import datastore
from googledatastore import helper as datastore_helper, PropertyFilter
# datastore entities that we need to perform the mapping computations
#from models import UserPlan, UploadIntervalCount, RollingMonthlyCount
这是我的requirements.txt文件看起来像
$ cat requirements.txt
Flask==0.12.2
apache-beam[gcp]==2.1.1
gunicorn==19.7.1
google-cloud-dataflow==2.1.1
six==1.10.0
google-cloud-datastore==1.3.0
google-cloud
这是所有/lib目录。该/lib目录有以下
$ ls -1 lib/google/cloud

注意两个google.cloud.datastore和google.cloud.proto在/lib文件夹中。然而，这种进口线路工作正常
from google.cloud.proto.datastore.v1 import query_pb2
但是这一次失败
from google.cloud import datastore
这是例外（从谷歌的云计算数据流控制台采取在线）

为什么找不到包装？
必须在'setup.py'中安装外部依赖关系，并且应该在管道参数中指定此文件。 –
是google.cloud的外部依赖？是什么使它不同于安装在/ lib目录中的google.cloud.proto.v1.datastore依赖项，我无法访问？无论如何，我会试试看。我只需要将'google-cloud'添加到setup.py中的'REQUIRED_PACKAGES'列表中？ –
嘿@MarcinZablocki，你的回答是正确的，非常感谢你！我仍然困惑，为什么有些东西可以进入/ lib目录，并在appengine_config.py文件中链接，但其他东西必须在setup.py文件中。也许你可以扩展它，并把它写成一个完整的答案？ –
