文章。 这是一篇你真正开始前需要查阅的文章。 本文介绍了前后端工作原理，前后端搭建的流程、搭建过程中需要用到的技术以及 开发环境版本。 一、前后端如何工作 Django、Vue 和 Element UI 前后 端原理论述  作者：M&T. 2 《51 测试天地》七十四 www.51testing.com 后端开发（Django+Rest Framework+MySQL）： Django 与前端进行数据交互。 MySQL 是一个关系型数据库，用于存储后端的数据。 前端开发（Vue+Element UI）： Vue 是一种现代的 JavaScript 框架，用于构建用户界面。Vue 提供了丰富的组件和模 块，可以帮助开发者构建交互式的单页面应用（SPA）。 Element UI 是一个基于 Vue 的 UI 组件库，提供了丰富的预定义组件，用于快速搭建 美观的用户界面。

If step is positive, the last element is the largest start + i * step less than stop; if step is negative, the last element is the smallest start + i * step greater than stop. step

The architecture mini version of Anaconda that includes only conda and its dependencies. If you prefer to have conda plus over 7,500 open-source packages, install Anaconda. We recommend you install Anaconda for the local (set_build_id) By default, conda-build creates a new folder for each build, named for the package name plus a timestamp. This allows you to do multiple builds at once. If you have issues with long paths, you

They can be obtained environments Various operations involved with creating, updating, exporting, and removing environments, plus more Managing channels Information about channels and how they are searched through when installing (conda-build 3.0+) By default, conda-build creates a new folder for each build, named for the package name plus a timestamp.
