About npmnpm介绍
npm is the world's largest software registry. Open source developers from every continent use npm to share and borrow packages, and many organizations use npm to manage private development as well.npm是世界上最大的软件注册中心。来自各个大陆的开源开发人员都使用npm来共享和借用包，许多组织也使用npm管理私人开发。
npm consists of three distinct components:npm由三个不同的组成部分组成：
the website网站the Command Line Interface命令行界面 (CLI)the registry注册表
Use the website to discover packages, set up profiles, and manage other aspects of your npm experience. 使用该网站可以发现程序包、设置配置文件，并管理npm体验的其他方面。For example, you can set up organizations to manage access to public or private packages.例如，您可以设置组织来管理对公共或私有包的访问。
The CLI runs from a terminal, and is how most developers interact with npm.CLI从终端运行，是大多数开发人员与npm交互的方式。
The registry is a large public database of JavaScript software and the meta-information surrounding it.注册表是一个大型公共数据库，包含JavaScript软件及其周围的元信息。

Getting started起步
To get started with npm, you can create an account, which will be available at http://www.npmjs.com/~*yourusername*.要开始使用npm，您可以创建一个帐户，该帐户将位于http://www.npmjs.com/~*yourusername*。
After you set up an npm account, the next step is to use the command line interface (CLI) to install npm. 设置npm帐户后，下一步是使用命令行界面（CLI）安装npm。We look forward to seeing what you create!我们期待着看到你创造的东西！
Sharing packages and collaborating with others共享软件包并与他人合作
If you choose to share your packages publicly, there is no cost. 如果您选择公开分享您的包裹，则无需支付任何费用。To use and share private packages, you need to upgrade your account. 若要使用和共享私人软件包，您需要升级您的帐户。To share with others, create organizations, called npm organizations, and invite others to work with you, privately (for a fee) or publicly (for free).要与他人分享，请创建称为npm organizations的组织，并邀请他人私下（收费）或公开（免费）与您合作。
You can also use a private npm package registry like GitHub Packages or the open source Verdaccio project. 你也可以使用像GitHub Packages或开源Verdaccio项目这样的私人npm软件包注册表。This lets you develop packages internally that are not shared publicly.这允许您在内部开发不公开共享的包。
