Answer 1

Step1: Edit your package.json changing the line

@angular/cli": "1.6.4"

to

@angular/cli": "^1.6.4"

Step2:

npm update -g @angular/cli 

Step3:

npm install --save-dev @angular/cli@latest

I was facing the exact same problem. These three did the tasks for me. You may like to see https://github.com/angular/angular-cli/issues/9307
