安装Django

之前安装了python3的虚拟环境，这次在虚拟环境中安装Django

首先进入到虚拟环境，用pip来安装Django

进入虚拟目录

cd /virtualenvs/venv/

创建站点mysite

django-admin startproject mysite

创建应用blog

cd mysite/

python manage.py startapp blog

提示报错

(venv) [root@izm5e47qpndp7jfqjxvf13z mysite]# python manage.py startapp blog
Traceback (most recent call last):

参考网上的教程，但是找不到文件或命令错误

虽然安装了sqlite
