Answer 1

I had the same issue and all I needed to do was login to npm

npm login

or alternatively

npm add user // consult the documentation for the params  

Answer 2

After trying everything, including node/npm upgrade, cache cleaning and reverting code, nothing helped besides one simple thing: Turning OFF Windows 10's Real-time protection during the dev/build. Looks like latest updates made it super aggressive.

Answer 3

In my case, the problem was that, I did not install typescript. Although I did install Node and Angular. To check if you have installed typescript or not

Run this command: tsc -v

If not, then to install typescript

Run this command: npm install -g typescript

And, finally to install required dependencies

Run this command: npm install

in the root folder of the project.
