如何在Vue-cli项目中更改端口号，使其在另一个端口上运行而不是8080。
当前回答
虽然有点晚了，但我认为将所有这些答案整合成一个概述所有选项的答案是有帮助的。
分别在Vue CLI v2 (webpack模板)和Vue CLI v3中，按优先级(从高到低)排序。
Vue CLI v3
package.json: Add port option to serve script: scripts.serve=vue-cli-service serve --port 4000 CLI Option --port to npm run serve, e.g. npm run serve -- --port 3000. Note the --, this makes passes the port option to the npm script instead of to npm itself. Since at least v3.4.1, it should be e.g. vue-cli-service serve --port 3000. Environment Variable $PORT, e.g. PORT=3000 npm run serve .env Files, more specific envs override less specific ones, e.g. PORT=3242 vue.config.js, devServer.port, e.g. devServer: { port: 9999 }

Vue CLI v2(已弃用)
环境变量$PORT，例如:PORT=3000 / config / index.js: dev.port

进入“node_modules/@vue/cli-service/lib/options.js”目录 在“devServer”的底部，解锁代码 现在在“port”中给出你想要的端口号:)
devServer: {
open: process.platform === 'darwin',
host: '0.0.0.0',
port: 3000, // default port 8080
https: false,
hotOnly: false,
proxy: null, // string | Object
before: app => {}
}
如果你想改变localhost端口，你可以改变package.json中的scripts标签:
"scripts": {
"serve": "vue-cli-service serve --port 3000",
"build": "vue-cli-service build",
"lint": "vue-cli-service lint"
},
如果你想临时改变端口号，你可以在npm run serve命令中添加一个-port选项。
运行服务-- --端口6058
最好的方法是更新包中的serve脚本命令。json文件。只需像这样追加——port 3000:
"scripts": {
"serve": "vue-cli-service serve --port 3000",
"build": "vue-cli-service build",
"inspect": "vue-cli-service inspect",
"lint": "vue-cli-service lint"
},
