发布项目到npm

1.在官网注册帐号（https://www.npmjs.com/）

2.本地用户验证，在命令行执行,输入用户名密码和邮箱

npm adduser

 3.在本地用npm init生成pageage.json，填写相应的信息

{
  "name": "lin-xiaoji-learn-npmjs",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "repository": {
    "type": "git",
    "url": "git+https://github.com/lin-xiaoji/learn-npmjs.git"
  },
  "keywords": [
    "learn",
    "npmjs"
  ],
  "dependencies":{
    "classnames": "^2.2.1"
  },
  "author": "lin-xiaoji",
  "license": "MIT",
  "bugs": {
    "url": "https://github.com/lin-xiaoji/learn-npmjs/issues"
  },
  "homepage": "https://github.com/lin-xiaoji/learn-npmjs#readme"
}

 4.编写好模块逻辑代码，然后执行

npm publish

执行完后，正常情况下，就能成功发布到npmjs.com上面，可以登陆帐号查看是否成功

如果出现 publish Failed PUT 403错误，一般是名称已存在，或者是版本号没有增加

5.删除一个项目,或删除某个版本

npm unpublish [email protected]
