npm info命令可以查看哪些包属性？
在当今的软件开发领域，npm（Node Package Manager）已经成为JavaScript生态系统中最受欢迎的包管理工具。它不仅提供了丰富的第三方库和框架，还极大地提高了项目的开发效率。而npm中的npm info命令则是一个强大的功能，可以帮助开发者快速了解所需包的详细信息。那么，npm info命令可以查看哪些包属性呢？本文将为您一一揭晓。
1. 包名称和版本
使用npm info 命令，您可以直接查看指定包的名称和版本信息。例如，查询express包的信息：
npm info express
执行上述命令后，您将看到如下输出：
name: express
version: 4.17.1
description: Fast, unopinionated, minimalist web framework for Node.js
这里，name表示包的名称，version表示包的版本号，description则是对包的简要描述。
2. 包的发布者
通过npm info 命令，您还可以了解包的发布者信息。这包括包的作者、维护者以及所属的组织。
npm info express
输出结果中，author和maintainers字段分别列出了包的作者和维护者信息。例如：
author: TJ Holowaychuk (http://github.com/tj)
maintainers: [ 'tj@visionmedia.com', 'burnerscott@gmail.com', 'rauchg@gmail.com', ... ]
3. 包的依赖关系
了解一个包的依赖关系对于确保项目兼容性和稳定性至关重要。npm info 命令可以帮助您查看包的依赖关系。
npm info express
输出结果中，dependencies字段列出了该包的直接依赖项。例如：
