Cannot use relative folder structure in NPM packages.json

Im using the example flask/react app from this github https://github.com/Faruqt/React-Flask

Problem is I have the flask.exe in Project/venv/scripts folder
and the repository is in Project/React-Flask-master fodler

I edited the Prackges.json to

  "scripts": {
    "start": "react-scripts start",
    "temp": "cd ../",
    "start-backend": "cd backend && /../../venv/Scripts/flask run --no-debugger",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },

But no matter what I try, I cannot use the relative folder structure.

I added a “temp” lien that is supposed to go one folder up, and even that doesnt work

(venv) C:CodeProjectReact-Flask-master>npm run temp

> [email protected] temp
> cd ../


(venv) C:CodeProjectReact-Flask-master>

And

(venv) C:CodeaicodeAIbotscatgptReact-Flask-master>npm run start-backend

> [email protected] start-backend
> cd backend && /../../venv/Scripts/flask run --no-debugger

The system cannot find the path specified.

(venv) C:CodeaicodeAIbotscatgptReact-Flask-master>

I tried using “../../” and “/../../”
