Question

我正在尝试在django现有数据库中集成弹性。但是在站点包中，我在运行本地服务器或查看相应命令时遇到错误。

以下是我正在使用的软件包的版本， django-elasticsearch-dsl == 0.5.0，elasticsearch == 6.3.0和elasticsearch-dsl == 6.2.1。

  File "manage.py", line 22, in <module>
    execute_from_command_line(sys.argv)
  File "Desktop/envs/elas_envs/lib/python3.6/site-packages/django/core/management/__init__.py", line 363, in execute_from_command_line
    utility.execute()
  File "Desktop/envs/elas_envs/lib/python3.6/site-packages/django/core/management/__init__.py", line 337, in execute
    django.setup()
  File "/homeDesktop/envs/elas_envs/lib/python3.6/site-packages/django/__init__.py", line 27, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "/home/Desktop/envs/elas_envs/lib/python3.6/site-packages/django/apps/registry.py", line 85, in populate
    app_config = AppConfig.create(entry)
  File "/home/Desktop/envs/elas_envs/lib/python3.6/site-packages/django/apps/config.py", line 94, in create
    module = import_module(entry)
  File "/home//Desktop/envs/elas_envs/lib/python3.6/importlib/__init__.py", line 126, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "<frozen importlib._bootstrap>", line 994, in _gcd_import

  File "<frozen importlib._bootstrap_external>", line 678, in exec_module
  File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed
  File "/home/Desktop/envs/elas_envs/lib/python3.6/site-packages/django_elasticsearch_dsl/__init__.py", line 3, in <module>
    from .documents import DocType  # noqa
  File "/home/Desktop/envs/elas_envs/lib/python3.6/site-packages/django_elasticsearch_dsl/documents.py", line 8, in <module>
    from elasticsearch_dsl.document import DocTypeMeta as DSLDocTypeMeta
ImportError: cannot import name 'DocTypeMeta'

谢谢。

这个问题来自将近两年前，但这可以帮助其他人。在最新版本的django_elasticsearch_dsl中，您需要使用文档：

from django_elasticsearch_dsl import (
    Document,
    fields,
    Index,
)

Answer 2

就像this issue中所述，这是由于elasticsearch-dsl软件包从版本6.2.0开始缺乏向后兼容性的结果。临时解决方案是在破坏更改之前仅使用旧版本的软件包：

pip install elasticsearch-dsl==6.1.0

希望这会很快解决。
