AttributeError: 'module' object has no attribute 'lru_cache'

I_Like_AI

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
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/home/leo/django/setup.py", line 32, in <module>
        version = __import__('django').get_version()
      File "django/__init__.py", line 1, in <module>
        from django.utils.version import get_version
      File "django/utils/version.py", line 60, in <module>
        @functools.lru_cache()
    AttributeError: 'module' object has no attribute 'lru_cache'
怎么修复这个错误？

上条把妹之手

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/
