SAP Hybrid App Toolkit Installation Problem (Mac)

Hi Experts,

I'm trying to install the SAP Hybrid App Toolkit, but I'm receiving an ERROR:

"Cordova search plugin failure: you must configure the the HTTP(S) proxy correctly."

I tried to configure the Plugman and it seems to be okay. But if check it again, it's still the same error.

Even after restarting my Mac.

Do you have any ideas?
