You can use npm install and npm run dev if you prefer

"server": "set NODE_ENV=production&&nodemon app.js"
remove space (run on windows)

[ZamanMehdi]

still not working

[wk989898]

solved on windows:
if you run dev , modify "dev": "concurrently -n 'server,client' -c 'red,green' \"nodemon app.js\" \"set NODE_ENV=dev&& set PORT=8000&&react-scripts start\""
if you run server,make sure you build it and modify "server": "set NODE_ENV=production&&nodemon app.js"

Hello sir, I have faced the same issue. But you can see that error shows that "NODE_ENV" is not recognized.
So, you can install it in that project by following command - "npm install -g win-node-env". Then try "yarn run dev".
That worked for me and also should fix your issue
