如何在npm中查看包的特定版本发布时间？

随着前端技术的发展，各种前端框架和库层出不穷。npm（Node Package Manager）作为前端开发者常用的包管理工具，为我们提供了丰富的资源。然而，在使用npm时，我们常常会遇到一个问题：如何查看包的特定版本发布时间？本文将为您详细介绍如何在npm中查看包的特定版本发布时间。

一、使用npm命令查看

在npm中，我们可以通过以下命令查看包的特定版本发布时间：

npm view [package-name] versions

这条命令会列出该包的所有版本信息，包括版本号和发布时间。例如，查看lodash包的所有版本信息：

npm view lodash versions

执行上述命令后，您会得到类似以下的结果：

[

  '4.17.15',

  '4.17.14',

  '4.17.13',

  '4.17.12',

  '4.17.11',

  '4.17.10',

  '4.17.9',

  '4.17.8',

  '4.17.7',

  '4.17.6',

  '4.17.5',

  '4.17.4',

  '4.17.3',

  '4.17.2',

  '4.17.1',

  '4.17.0',

  '4.16.6',

  '4.16.5',

  '4.16.4',

  '4.16.3',

  '4.16.2',

  '4.16.1',

  '4.16.0',

  '4.15.0',

  '4.14.0',

  '4.13.0',

  '4.12.0',

  '4.11.0',

  '4.10.0',

  '4.9.0',

  '4.8.0',

  '4.7.0',

  '4.6.0',

  '4.5.0',

  '4.4.0',

  '4.3.0',

  '4.2.0',

  '4.1.0',

  '4.0.0',

  '3.10.1',

  '3.10.0',

  '3.9.3',

  '3.9.2',

  '3.9.1',

  '3.9.0',

  '3.8.0',

  '3.7.0',

  '3.6.0',

  '3.5.0',

  '3.4.0',

  '3.3.4',

  '3.3.3',

  '3.3.2',

  '3.3.1',

  '3.3.0',

  '3.2.3',

  '3.2.2',

  '3.2.1',

  '3.2.0',

  '3.1.0',

  '3.0.3',

  '3.0.2',

  '3.0.1',

  '3.0.0',

  '2.4.1',

  '2.4.0',

  '2.3.3',

  '2.3.2',

  '2.3.1',

  '2.3.0',

  '2.2.3',

  '2.2.2',

  '2.2.1',

  '2.2.0',

  '2.1.0',

  '2.0.3',

  '2.0.2',

  '2.0.1',

  '2.0.0',

  '1.4.1',

  '1.4.0',

  '1.3.3',

  '1.3.2',

  '1.3.1',

  '1.3.0',

  '1.2.1',

  '1.2.0',

  '1.1.0',

  '1.0.3',

  '1.0.2',

  '1.0.1',

  '1.0.0'

]

从上述结果中，我们可以看到每个版本的发布时间。例如，lodash包的4.17.15版本发布于2021年1月11日。

二、使用npm view命令查看

除了上述命令外，我们还可以使用以下命令查看包的特定版本发布时间：

npm view [package-name] [version-number]

这条命令会列出指定版本的详细信息，包括发布时间。例如，查看lodash包的4.17.15版本信息：

npm view lodash 4.17.15

执行上述命令后，您会得到类似以下的结果：

{

  "name": "lodash",

  "version": "4.17.15",

  "description": "A modern JavaScript utility library delivering consistency across all JavaScript environments.",

  "main": "index.js",

  "publish_time": "2021-01-11T20:00:01.872Z",

  "dist": {

    "tarball": "https://registry.npmjs.org/lodash/-/lodash-4.17.15.tgz",

    "shasum": "a8b5e2e5b0e8c3975a7b9e9e6a9f9c6a9e9e6a9f9c6a9e6a9f9c6a9e9e6a9f9c6a9e9e6a9f9c6a9e9e6a9f9c6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e9e6a9e
