Cannot find module @angular-devkit/core

Can you explain why doing npm install doesn't take care for the angular-cli issues and I have to manually mangle with the installation process? Especially on a mean seed repo.

This error related to Angular-CLI, you can send them an issue. It's come with latest Angular-CLI and Angular 5 and not happening on the first version of Angular-CLI 1.5 and Angular 5.

Try this:

1. npm update -g @angular/cli
2. editing my package.json changing the line:
   "@angular/cli": "1.6.0",
   to
   "@angular/cli": "^1.6.0",
3. npm update
