是fis3的熱更新監聽8080嗎？

vue-cli里基本包括了這些功能，我認為沒必要再用fis3，不知道你用fis3的目的是什么？

如果非要用，你可以在config里找到項目的端口改一下。

config/index.js

// see http://vuejs-templates.github.io/webpack for documentation.

var path = require('path')

module.exports = {

? build: {

? ? env: require('./prod.env'),

? ? index: path.resolve(__dirname, '../dist/index.html'),

? ? assetsRoot: path.resolve(__dirname, '../dist'),

? ? assetsSubDirectory: 'static',

? ? assetsPublicPath: '/',

? ? productionSourceMap: true,

? ? // Gzip off by default as many popular static hosts such as

? ? // Surge or Netlify already gzip all static assets for you.

? ? // Before setting to `true`, make sure to:

? ? // npm install --save-dev compression-webpack-plugin

? ? productionGzip: false,

? ? productionGzipExtensions: ['js', 'css']

? },

? dev: {

? ? env: require('./dev.env'),

? ? port: 8080,

? ? assetsSubDirectory: 'static',

? ? assetsPublicPath: '/',

? ? proxyTable: {},

? ? // CSS Sourcemaps off by default because relative paths are "buggy"

? ? // with this option, according to the CSS-Loader README

? ? // (https://github.com/webpack/css-loader#sourcemaps)

? ? // In our experience, they generally work as expected,

? ? // just be aware of this issue when enabling this option.

? ? cssSourceMap: false

? }

}

在config文件里修改端口?

我用的是fis3前端構建工具，fis3他會默認的占用8080端口，如果端口被占用的了話，npm run dev 也會報錯的?
