Python 名称错误：名称'；基数'；未定义（干草堆搜索）

我想在django应用程序中包含全文搜索。我正在为此使用whoosh haystack。当我在已安装的应用程序中包括whoosh和haystack，并执行命令./manage.py时，我收到一个导入错误。有人能解决这个问题吗

settings.py
INSTALLED_APPS = {
   'django.contrib.admin',
   'django.contrib.auth',
   'django.contrib.contenttypes',
   'django.contrib.sessions',
   'django.contrib.messages',
   'django.contrib.staticfiles',
   'search',
   'whoosh',
   'haystack',
 }

在我的模型中进行迁移时，我得到的错误是：

my models.py：

 from django.contrib.auth.models import User
 from django.db import models

 class Author(User):
      pass

 class Book(models.Model):
      title = models.CharField(max_length=300)
      author = models.ForeignKey(Author)
      isbn = models.CharField(max_length=300)
      resume = models.TextField()

      def __unicode__(self):
          return self.title

有关更多信息，我使用django pip安装方法在django项目中安装haystack和whoosh，如下所示：

pip install haystack
pip install whoosh

回溯很清楚：

File "C:\Users\Samad Talukder\Desktop\django-env\search\search\settings.py", line 80, in <module>
    'PATH': os.path.join(base(), 'whoosh_index')
    NameError: name 'base' is not defined

文件“C:\Users\Samad Talukder\Desktop\django env\search\search\settings.py”，第80行，在
'PATH'：os.PATH.join（base（），'whoosh_index'）
NameError:未定义名称“base”

---

这意味着settings.py文件的第80行使用了一个未定义的名称（

base

——显然应该是一个函数）。设置文件缺少导入或函数定义。

base

应该做什么etc超出了我们的知识范围（它肯定不是内置的，在django设置文件中也不是标准的），但现在应该这样做，因为它是您的项目

你定义了base（）函数吗？不，我不理解base函数。请解释一下。PATH:os.PATH.join（base（），'whoosh_index'）@ABDULNIYASPM-see
