node_modules deleting dependency automatically

I'm following an angular project where the start of the project is published at github

I forked this and made a clone on my local machine (OS windows 11). pre-requisites : install python.

The guide tells me to run the following commands.

npm install npm run-script build

//////////////////////////////it end up with below errors///////////////
