发布自己的NPM包

1 注册自己的 npm 账号

• 进入 npm 官网注册账号

2 登录账号

npm login

3 安装 nrm

npm install nrm -g
nrm ls
nrm use npm

4 创建项目文件夹

mkdir js-tools && cd js-tools

5 npm 初始化

npm init -y

6 配置 package.json

{
  "name": "wxdxjs-tools",
  "version": "1.0.0",
  "description": "this is my first package",
  "main": "index.js",
  "private": false,
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "chenwei",
  "license": "ISC"
}

7 创建 README.md

this is my package

8 创建 index.js

module.exports = {
    printMsg: function () {
        console.log('this message is from yuyy-test-pkg!');
    }
}

目录结构

── js-tools
    ├── README.md
    ├── index.js
    └── package.json

9 npm 发布

npm publish

10 版本迭代

❝

需要修改 package.json 的版本号，每次根据需求增加

❞

+ "version": "1.0.0"
- "version": "1.0.1",

11 npm 取消发布

npm unpublish wxdxjs-tools --force

可能报的错

code E402

402 Payment Required - PUT 
http://registry.npmjs.org/@dinghx%2funifiedValidator 
- You must sign up for private packages

这是因为包名是 @xxx/xxxx npm会认为要发布私包，私包需要收费，需将发布命令改成

npm publish --access public

code E403

code E403  没权限发布
npm ERR! [no_perms] Private mode enable, only admin can 
publish this module [no_perms] 
Private mode enable, only admin can publish
this module: your-package

这个是你的源设置成第三方源的时候才有可能发生，比如设置了淘宝源就可能会导致该问题。只要把源改回默认的就可以了，如下

npm config set registry http://registry.npmjs.org

包名相似

npm ERR! Package name too similar to existing packages; 
try renaming your package to '@dinghx/captcha' and publishing 
with 'npm publish --access=public' instead : your-package

邮箱没有校验

npm ERR! you must verify your email before publishing a new package
: https://www.npmjs.com/email-edit : your-package

这是邮箱没有校验，登录https://www.npmjs.com 重新发起邮箱验证
