@angular/cli not working after installation

Question

I have installed the @angular/cli on my MacBook machine. Node server version is v6.9.5 and the npm version is 3.10.10. I have ran the following command to install the @angular/cli.

sudo npm install -g @angular-cli

When I run the ng help command or any command for ng. It shows me the following error

Parsing .angular-cli.json failed. Please make sure your .angular-cli.json is valid JSON. Error: SyntaxError: Unexpected token u in JSON at position 22

InvalidConfigError: Parsing .angular-cli.json failed. Please make sure your 
.angular-cli.json is valid JSON.

I also uninstalled and @angualr/cli and clear the cache then reinstalled @angualr/cli. I run the following command.

sudo npm uninstall -g @angular-cli 
npm cache clean sudo 
npm install -g @angular-cli

Still the same issue is appearing.

The package is called @angular/cli, so do npm install -g @angular/cli.
