title: Trouble updating to Angular 6
body: <p>I am trying to update to Angular 6 from 5.2. I use yarn and have updated angular cli both local and global to latest version. I have node 8.</p>
  
  <p>When I run any of the following commands:</p>
  
  <p>ng update @angular/core</p>
  
  <p>ng update @angular/material</p>
  
  <p>ng update</p>
  
  <p>Absolutely nothing happens...just starts a new line in the terminal.
  Why is this happening, and what do I need to do update to Angular 6?</p>
