Vue+Django REST framework前后端分离平台开发之项目初始化

Posted 2022-07-28 bk770466199

项目初始化

系统环境

python 3.7.3

Django 2.2.4

DjangoRestFramework 3.10.2

 

第一步：启动虚拟化环境

virtualenv虚拟化环境搭建：https://www.cnblogs.com/bk770466199/p/11366374.html

第二步：安装相关依赖包

#查看当前安装依赖包列表
    pip list
#豆瓣源加速安装Django
    
    pip install -i https://pypi.douban.com/simple django
    
    虽然pycharm的设置里可以安装依赖包，但是有些依赖包下载过慢，用豆瓣源加速安装，在命令行里面安装好相关的包，再在pycharm里生成项目，避免因下载包过慢卡死。

#pip安装DRF
    
    pip install djangorestframework

 

第三步：pycharm生成项目

 

创建mysql数据库

配置setting,使用我们创建的数据库启动Django项目

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。
