npm start not working Angular

[hiyamgh]

When I am putting npm start in VSCode, I get the following error:

`> mean@1.0.0 start C:\Users\User\Desktop\MontHolding\mean

@DanielRuf Thank you for your reply, but the same error appeared again when I was installing windows build tools :/

[hiyamgh]

I will try to reinstall, but I don't understand why Python is related to this !!

[hiyamgh]

@DanielRuf I did this, I also added the node.js to PATH in Environment Variables and rebooted the system, but again I'm still getting the same error

[kenany]

Can you try changing your "start" script (in your package.json) to:

"start": "node app.js"

[hiyamgh]

@kenany I did this, but still getting the error.

@hiyam97 Can I see the error log after making my suggested change?
