react 项目package.json更改启动端口

我使用的是roadhog来启动前段react服务，日常中我们经常会需要启动多个项目，端口会经常冲突，为了方便开发，这边我们要修改启动端口：

将scripts中的start命令“roadhog server” 变更为 “set port=8808 && roadhog server”

如果还是不行，那么可以尝试更换为“export PORT=8808 && roadhog server”

{
  "private": true,
  "scripts": {
    "start": "roadhog server",
    "build": "npm run lint && roadhog build",
    "lint": "standard src/**/*.js && stylelint src/**/*.css",
    "precommit": "npm run lint"
  },
