如何利用npm info命令获取包的构建依赖
在当今的软件开发领域，依赖管理是确保项目顺利进行的关键环节。其中，npm（Node Package Manager）作为JavaScript生态系统中最受欢迎的包管理工具，被广泛用于管理项目依赖。本文将深入探讨如何利用npm info命令获取包的构建依赖，帮助开发者更好地理解和管理项目依赖。
一、npm info命令概述
npm info命令是npm提供的用于查看包信息的命令，可以查询到包的版本、描述、关键词、依赖关系等信息。在获取包的构建依赖方面，npm info命令具有极高的实用价值。
二、获取包的构建依赖
要获取某个包的构建依赖，可以使用以下命令：
npm info dependencies
其中，express包的构建依赖，可以使用以下命令：
npm info express dependencies
执行上述命令后，将输出express包的所有构建依赖，如下所示：
