You're using "[email protected]" which won't work with angular 2.3.x

[abhinaypandey]

thanks @scttcper . That worked like charm.

Hey guys I'm facing same issue with Angular 2.4.9.. any ideas?

Current behavior
/modules/@angular/compiler-cli/src/version.ts:19
export const VERSION = new Version('2.4.9');
^

Expected behavior
normal "npm install" process

Minimal reproduction of the problem with instructions
When I'm adding "@angular/compiler-cli": "2.4.9", to the package.json and executing "npm install" the above error arise.

What is the motivation / use case for changing the behavior?

Please tell us about your environment:
node v7.6.10
npm v3.10.8

• Angular version:
  2.4.9
