Question

要启动我的节点服务器，我必须在不同的终端选项卡中运行：

redis-server
mongod
nodemon app/app.js

我试图在package.json中为这些脚本制作一个脚本，如下所示：

"start": "redis-server && mongod && nodemon app/app.js"

但是在npm start上，我收到下一个错误：

> server@1.0.0 start /Users/razbuchnik/Projects/taxi4you/server
> redis-server && mongod && npm run dev

我建议两个npm脚本。但是，如果您真的想要它：

label

{ ... "start": "redis-server 2>&1 & mongod 2>&1 & nodemon app/app.js" }应该将Redis和mongo的2>&1重定向到stderr中，这样您就可以在输出中出现错误

npm脚本可同时运行redis-server，mongod和nodemon
