无法通过终端下载Django

Question

我试图通过终端下载并安装Django.为此,我运行了这个命令:

sudo pip install Django 

但是,这会产生以下错误:

Collecting Django

    Complete output from command python setup.py egg_info:

Answer 1

Django 2.0与小于3.4的Python版本不兼容

lru_cache() 是在Python 3.2中引入的,所以你使用的Python版本太旧了.

如果你需要支持Python 2.7,请尝试Django 1.11,因为这是支持它的最后一个版本:

pip install "django~=1.11.9"
