How to fix the error "npm ERR! Peer dep missing: @ angular ..."?

[varlok]

Hello everybody. Did everything according to the instructions. With the command "npm start" I receive messages:

And at the end of the "build error".

What is the reason and how to fix it?##

[dvuika]

The "npm ERR! peer dep missing" is often raised by NPM versions before 5.x and are not important for the build/start process. The application should still run. If it's not running please share the full npm error log so we could detect the real source of the problem easier.

The real error is in the middle and says:

I suspect this is the same global TypeScript problem everyone is getting since yesterday (MS released a version that broke many projects out there).

I suggest removing node_modules, updating "package.json" file and pinning typescript version to "2.3.4" (no extra symbols), and then running "npm install" and "npm start" once again.
