安装flask
现在开始安装 Flask 以及一些我们会用到的扩展。首选的方式就是创建一个虚拟环境，这个虚拟环境能够安装所有的东西，而你的系统主Python不会受到影响。另外一个好处就是这种方式不需要你拥有root权限。
mkdir microblog
cd microblog/
python3 -m venv flask
cd flask/
bin/pip install flask
bin/pip install flask-login
bin/pip install flask-openid
bin/pip install flask-mail
bin/pip install flask-sqlalchemy
bin/pip install sqlalchemy-migrate

安装gunicorn
