Ionic serve unexpectedly closed on macOS X (npm issue) - macos

Question

I installed npm ionic cordova on MacOS X 10.13
sudo npm install -g cordova ionic
Then I ran
ionic serve
and got an error suggesting to do :
sudo chown -R $USER:$(id -gn $USER) /Users/admin/.config
which I did.
And now I can't run ionic serve:
$ ionic serve
