How do I correctly upgrade angular 2 (npm) to the latest version?

Question

Recently I started Angular 2 tutorial at https://angular.io/docs/ts/latest/tutorial/.

and left off with Angular 2 beta 8. Now I resumed the tutorial and latest beta

Answer 1

Official npm page suggest a structured method to update angular version for both global and local scenarios.

1.First of all, you need to uninstall the current angular from your system.

npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
npm uninstall -g @angular/cli

2.Clean up the cache

npm cache clean

EDIT

As pointed out by @candidj

npm cache clean is renamed as npm cache verify from npm 5 onwards

3.Install angular globally

npm install -g @angular/cli@latest

4.Local project setup if you have one

rm -rf node_modules
npm install --save-dev @angular/cli@latest
npm install

Please check the same down on the link below:

This will solve the problem.
