如何使用NPM脚本在package.json中运行/启动json服务器和活动服务器？

Question

我有一个带有html/css/javascript文件的项目，我想输入命令npm start来运行json-server和活服务器。

我尝试了以下命令："start": "json-server --watch db.json && live-server"，但它只启动第一个命令，而不是同时启动两个命令。

package.json

{
  "name": "testa-npm-live-server",
  "version": "1.0.0",
  "description": "",
  "main": "",
  "dependencies": {},
  "devDependencies": {
    "json-server": "^0.16.1",
    "live-server": "^1.2.1"
  },
  "scripts": {
    "start": "json-server --watch db.json && live-server"
  },
  "author": "",
  "license": "ISC"
}

IDE: vscode

节点版本: v12.18.1

国家预防机制版本: 6.14.5

使用兼在paralell中运行命令。&&以串行/顺序运行，即第二个命令只在第一个命令运行完之后才启动。

{
  "name": "testa-npm-live-server",
  "version": "1.0.0",
  "description": "",
  "main": "",
  "dependencies": {},
  "devDependencies": {
    "concurrently": "^5.2.0",
    "json-server": "^0.16.1",
    "live-server": "^1.2.1"
  },
  "scripts": {
    "start": "concurrently \"json-server --watch db.json\" \"live-server\""
  },
  "author": "",
  "license": "ISC"
}
