非常简单，只要加一个配置！第1步，复制这个代码（端口可改）
"config": {

"nuxt": {

"host": "0.0.0.0",

"port": "8090"

}
},
"config": {

"nuxt": {

"host": "0.0.0.0",

"port": "8090"

}
},第2步，找到根目录下的package.json，把代码粘贴进去。这是全部的代码，我这里配置在了8~13行。
{
"name": "guanWangPhone",
"version": "1.0.0",

"private": true,

"config": {

"nuxt": {

"host": "0.0.0.0",

"port": "8090"

}
},

"scripts": {

"dev": "cross-env NODE_ENV=development nodemon server/index.js --watch server",

"build": "nuxt build",

"start": "cross-env NODE_ENV=production node server/index.js",

"generate": "nuxt generate"
},

},
"devDependencies": {

"sass-loader": "^8.0.0",

"scss-loader": "0.0.1"
}
}
