I struggled with the same problem just a minute ago. My project was generated using the v 1.6.0 of angular-cli.
npm update -g @angular/cli
editing my package.json changing the line
"@angular/cli": "1.6.0",
to
"@angular/cli": "^1.6.0",
npm update
did the trick.

    https://github.com/angular/angular-cli/issues/9307
 sudo npm update -g @angular/cli
/usr/bin/ng -> /usr/lib/node_modules/@angular/cli/bin/ng

> @angular/cli@6.0.1 postinstall /usr/lib/node_modules/@angular/cli
> node ./bin/ng-update-message.js
