AttributeError: 'module' object has no attribute 'lru_cache'
我通过以下方式安装django:git clone git://github.com/django/django.git
pip install -e django/
I use Ubuntu 16.04.
发生了以下错误
Obtaining file:///home/leo/django

怎么修复这个错误？ 上一个Django版本不支持python 2.7。如果您真的想要使用python 2.7和Django，您应该安装以前的Django版本。最新支持的是:1.11，因此，只需运行:pip install django==1.11 这是因为django版本需要python3解释器。因此，尝试使用pip3运行相同的命令
sudo apt-get -y install python3-pip
install pip3 sudo apt-get -y install python3-pip 可以使用git安装Python 2版本的Django
git clone git://github.com/django/django.git
cd django
git checkout 1.11.0
cd ..
pip install -e django/
Right > c:\Python27\Scripts>pip install django==1.11
Wrong > c:\Python27\Scripts>pip2.7 install django
c:\Python27\Scripts>pip2.7 install django
