I have tried the following option to resolve
Steps to resolve the issue

1. $ pwd
   it shows —> /Users/YourName /*** That is your Home path***/

Execute the below command to display the hidden files

2. $ defaults write com.apple.Finder AppleShowAllFiles true
3. $ killall Finder

After executing the above command you will see the hidden files.
if “.angular-cli.json” file exist under “/Users/yourname” (i.e Home Path) then remove “.angular-cli.json” file.

then navigate to your application path and try execute ‘ng’ command.
