ImportError：无法导入名称连接

Question

我想在我的django应用程序中包含全文搜索。我正在使用whoosh-haystack。当我在我安装的应用程序中包含whoosh和haystack，并执行命令./manage.py时，我收到导入错误。谁能解决这个问题。

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'whoosh',
    'haystack',
    'galleryApp',
    'galleryAdmin',
]

我得到的错误是

Answer 1

包haystack是相互矛盾的django-haystack。 （重新）移动它将解决问题。

有关详细信息，请参阅chat。

Answer 2

检查python __init__.py文件夹中是否有sitepackages/haystack文件。这可能是由于缺乏__init__.py。 __init__.py具有连接属性。如果没有，请尝试从github源卸载并安装/手动编写__init__.py文件。

Answer 3

以上对我不起作用。

对我有用的是：

• pip uninstall haystack
• pip uninstall django-haystack
• pip install django-haystack
