nuxt.js里路径被占用，怎么修改当前路径

在package.json文件里面添加

"config":{
    "nuxt":{
      "host":"localhost",//可以为本地路径
      "port":"3001"//自己定义
    }
 },

路径就变成http://localhost:3001

以下是示例

{
  "name": "nuxt-demo",
  "version": "1.0.0",
  "description": "Nuxt.js project",
  "author": "",
  "private": true,
  "scripts": {
    "dev": "nuxt",
    "build": "nuxt build",
    "start": "nuxt start",
    "generate": "nuxt generate",
    "lint": "eslint --ext .js,.vue --ignore-path .gitignore .",
    "precommit": "npm run lint"
  },
  "config":{
    "nuxt":{
      "host":"localhost",
      "port":"3001"
    }
  },
  "dependencies": {
    "nuxt": "^1.0.0"
  },
  "devDependencies": {
    "babel-eslint": "^8.2.1",
    "eslint": "^4.15.0",
    "eslint-friendly-formatter": "^3.0.0",
    "eslint-loader": "^1.7.1",
    "eslint-plugin-vue": "^4.0.0"
  }
}
