Answer 1

OS : Windows with Angular 4

"@angular/cli": "1.2.1"

"@angular/material": "2.0.0-beta.6"

I just removed the caret from above two dependencies and performed following steps, everything started working perfectly.

1. Remove node_module
2. Uninstall angular cli from local and global
3. Install the same version of angular cli in both
4. Do "npm install"
5. "ng serve"
