Mac os下Python3安装Django
1.查看pip版本 没有的话就是没安装成功 安装python的时候一般会自动安装pip
//pip版本
pip -V //对应python2.7
pip 9.0.1 from /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg (python 2.7)
pip3 -V //对应python3.6
pip 9.0.1 from /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (python 3.6)
2.用pip3/Python3安装Django，1.11.7是最新稳定版(官网download页面有 https://www.djangoproject.com/download )
这里注意用sudo 不然会报错
sudo pip3 install Django==1.11.7
提示 ：
You are using pip version 9.0.1, however version 19.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
需要在执行pip install --upgrade pip更新之后
sudo pip3 install Django==1.11.7

Uninstalling Django-2.1:

3.测试是否安装成功
cd /Users/z/PyP/Django
4.新建一个服务
sudo django-admin.py startproject testLocalHost
cd testLocalHost
5.运行服务，因为是用pip3/python3安装的Django 所以应该用python3来运行
python3 manage.py runserver
报错了。
...xxx .....xxx django.db.utils.OperationalError: unable to open database file
6.改用管理员权限运行：
sudo python3 manage.py runserver
打印：
