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创建一个vue.config.js，内容如下。
module.exports = {
devServer: {
port: 8080, // 端口号
}
};
