Project Initialization
System Environment
python 3.7.3
Django 2.2.4
DjangoRestFramework 3.10.2
Step one: Start the virtual environment
virtualenv virtualized environments built: https: //www.cnblogs.com/bk770466199/p/11366374.html
Step 2: Install dependent packages
# View the list of currently installed dependencies PIP List # watercress speed up installation source Django PIP install -i https://pypi.douban.com/ the Simple Django although pycharm setting where you can install the dependencies, but some rely package download is too slow, with watercress source speed up installation, at the command line related packages installed inside, and then build the project in pycharm, the download package to avoid slow stuck. # PIP installation DRF PIP install djangorestframework
The third step: pycharm build the project
Create a mysql database
Configuration setting, start using the database we created Django project
DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': "myshop", 'USER': "root", 'PASSWORD': "12345678", 'HOST': "127.0.0.1", "OPTIONS": {"init_command": "SET default_storage_engine=INNODB;"} } }
数据库的配置从网上都可以搜到，生产环境中可以根据系统类型分别配置，使得测试环境和生产环境可以分别连接对应的数据库。
安装mysqlclient
python连接mysql需要安装依赖包mysqlclient。
正常使用豆瓣源加速安装会报错，如下：

之前没有安装Microsoft Visual Studio 14.0的时候，是因为python3是依赖Microsoft Visual Studio 14.0解析的，需要安装Microsoft Visual Studio 14.0，安装完成之后就报这样的错，各种百度无果，祭出绝招：
一个神奇的网站：https://www.lfd.uci.edu/~gohlke/pythonlibs/
通过这个网站我下载了对应版本的whl文件，然后pip install,真的就不报错，成功安装。
