以获取更多信息。较新版本的 Python 内置一个轻量级的数据库 SQLite，所以你暂时不需要配置 数据库。 可以从 Python 官网或者系统的包管理工具获取到最新版的 Python。 Jython 上的 Django 如果你使用的是 Jython（一种 Java 平台的 Python 实现），你需要做一些额外的步骤。查看在 Jython 上运行 Django 获 取详细信息。 你可以在终端下输入命令 你可以在终端下输入命令 python 来验证是否已经安装 Python；你应该看到下面的信息： 1. Python 3.4.x 2. [GCC 4.x] on linux 3. Type "help", "copyright", "credits" or "license" for more information. 4. >>> 只有当你需要使用“大型”数据库例如 PostgreSQL、MySQL PostgreSQL、MySQL 或 Oracle 时，才需要这一步。若要 安装这样的数据库，请参考数据库安装信息。 快速安装指南 安装 Python 配置数据库 快速安装指南 - 13 - 本文档使用 书栈(BookStack.CN) 构建 如果你是从旧版本的 Django 升级安装，你将需要在安装新版本之前卸载旧版本的 Django。 你可以按下面三个简单的方式来安装 Django： 安装官方发布版本。对大多数用户来说这是最好的方式。

的错误。 提高项目可移植性：将项目的依赖放在虚拟环境中，可以使得项目在不同的计算机 或服务器上都能轻松地部署和运行，而不需要担心依赖问题。 简化依赖管理：虚拟环境可以将项目所需的依赖以及其版本信息保存在一个文件中 （例如 Pipfile.lock），这样可以方便地重现项目的开发环境，使得依赖的安装和管理更加 简单和自动化。 2、Pipenv 介绍 Pipenv 是 Python 的一 安装项目依赖时，它会自动创建一个虚拟环境， 确保项目的依赖不会与其他项目冲突。 5 《51 测试天地》七十四 www.51testing.com 管理依赖：Pipenv 会自动地管理项目的依赖关系，并将依赖信息保存在 Pipfile 和 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 构建工具和其他相关资源。以下是 npm 在前端开发中的应用介绍： 依赖管理：npm 可以管理前端项目的依赖，开发者可以在项目的 package.json 文件中 声明项目所依赖的第三方模块和库，以及其版本信息。在安装项目时，运行 npm install 命令会自动从 npm 仓库下载并安装这些依赖，使得项目能够在开发和生产环境中正常运 行。 脚本执行：在 package.json 文件中，开发者可以定义各种自定义的脚本命令，比如启
