django - 属性错误: 'module' object has no attribute 'lru_cache'

Question

在此环境设置中，我收到了如标题所示的错误。Apache2 与 mod_wsgi ，Python 3.5，Django 2.0.2 。我正在使用 virtualevn。

我的虚拟环境位于:/home/santosh/Documents/project/project/django 应用程序位于/home/santosh/Documents/project/Reports

下面是wsgi.py文件的内容

import os, sys


sys.path.append('/home/santosh/Documents/project/Reports/Reports')
sys.path.append('/home/santosh/Documents/project/Reports')


sys.path.append('/home/santosh/Documents/project/project/lib/python3.5/site-packages')
sys.path.append('/home/santosh/Documents/project/project/lib/python3.5')
sys.path.append('/home/santosh/Documents/project/project/bin')



from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "Reports.settings")

application = get_wsgi_application()

我跑了

sudo apt remove  libapache2-mod-wsgi
sudo apt install libapache2-mod-wsgi-py3

在Ubuntu 18.04上安装Python3版本，然后重新加载Apache，这为我解决了错误。
