Question

我有一个django应用，我正在尝试使用django-haystack，所以如下所示

已安装django-haystack

pip install django-haystack

已安装Whoosh

pip install Whoosh(https://bitbucket.org/mchaput/whoosh/wiki/Home)
            also tried
downloading from https://pypi.python.org/pypi/Whoosh/#downloads

所以，当我尝试pip freeze时，我能够看到输出版本为Whoosh==2.5.6

Django haystack设置

HAYSTACK_SITECONF = 'proj-web.search_sites'
HAYSTACK_SEARCH_ENGINE = 'whoosh'
HAYSTACK_WHOOSH_PATH = (os.path.join(os.path.dirname(__file__), 'search_index/'))

当我试图运行服务器时，我在浏览器中看到以下错误消息

Traceback:

Exception Type: MissingDependency at /
Exception Value: The 'whoosh' backend requires the installation of 'Whoosh'. Please refer to the documentation.

那么如何解决上述错误？为什么它要求Whoosh，即使它已经安装了？

我看到您的项目中有haystack个模块（/home/user/user/apps/proj-web/proj_name/haystack/）。删除此文件夹，激活您的virtualenv并运行：

pip uninstall django-haystack && pip install django-haystack

确保一切正常。

然后尝试像这样配置你的干草堆：

import os
HAYSTACK_CONNECTIONS = {
  'default': {
    'ENGINE': 'haystack.backends.whoosh_backend.WhooshEngine',
    'PATH': os.path.join(os.path.dirname(__file__), 'search_index'),
  },
}

使用django-haystack飞快移动使用/错误
