The error UNMET PEER DEPENDENCY @angular/[email protected] means you need to update your package.json to reference the @Angular packages at version 5.2.9 e.g. "@angular/animations": "^5.2.9". I would recommend updating ALL of the @angular packages to 5.2.9 — Simply Ged
I have managed to create a new angular app and instal jspdf without seeing that error. I siggest you delete your ‘node_modules’ folder and run ‘npm i’ to reinstall them all. — Simply Ged

I too was getting UNMET PEER DEPENDENCY @angular/[email protected] invalid error whenever i tried to install any other package(eg. npm install angular4-datepicker).

My npm -v was 3.x.x . So i upgraded my npm to 5.6.0 by installing the latest node.js from https://nodejs.org/en/ and it fixed the above issue for me.
