新建flask项目的一些步骤

项目环境：mac10.13 python365

pip install cookiecutter
cookiecutter https://github.com/sloria/cookiecutter-flask.git
pip install -r requirements/dev.txt
#注意webpack，不用就删掉对应的扩展删除略

#还要注意一下database.py的封装，外键不能为空的选项可能会报错。

#创建虚拟环境
pip install virtualenv
python3 -m virtualenv venv
source venv/bin/activate


#2018-11-15和之前一样的bug
#报错ModuleNotFoundError: No module named 'MySQLdb'
pip install mysqlclient
#Python: MySQLdb and “Library not loaded: libmysqlclient.16.dylib”
#Library not loaded: libssl.1.0.0.dylib
#_mysql.cpython-36m-darwin.so  Reason: image not found

export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/
#设置环境变量DYLD_LIBRARY_PATH，直接在.env下添加
