vue项目怎么修改端口号

1.Vue 2.x

        config文件夹中有一个index.js其中部分内容如下，port即为端口号，在这里更改即可。

module.exports = {

  dev: {

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

    port: 8080,  // 端口号

    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,

   }

};

2.Vue 3.x

        Vue 3.x 中修改端口号则需要在项目根目录下的vue.config.js中加入如下内容：

module.exports = {

  devServer: {

    port: 8080,   // 端口号

  }

};

将端口号更改成你想要的即可。
