Rest Framework->数据库配置 简要说明： 安装相关包：在开始之前，首先需要安装 Python 和 pip，然后安装 Django 等相关包， 可以使用 pip 命令来安装。 创建工程：使用 Django 的命令行工具创建 Django 项目，例如：django-admin startproject projectname。 后端依赖（pipenv）创建虚拟环境：建议使用 pipenv 结构。 前端依赖（npm install）：在项目目录下执行 npm install 命令，安装项目所需的前端 4 《51 测试天地》七十四 www.51testing.com 依赖包，这些依赖包通常存储在 package.json 文件中。 前端服务配置启动：在项目目录下执行 npm run serve 命令，启动前端开发服务器， 可以在浏览器中预览项目。 三、关键技术介绍 1、后端 Pipfile.lock 文件中，这样可以确保项目在不同环境中安装相同的依赖版本。 简化依赖安装：使用 Pipenv 安装依赖非常简单，只需要运行一个命令即可，而不需 要手动管理依赖的安装。 提供更友好的命令行界面：Pipenv 提供了一组易于使用的命令，使得包管理和虚拟 环境管理更加直观和简便。 支持开发模式：Pipenv 支持将项目的开发依赖和运行时依赖分开，这样可以减少项 目打包时的冗余依赖。
