I am very new to mobile development and am trying to get head start in cordova Ionic project in VS2015. I installed all the necessary components and started a new project of type ionic tabbed template (which I got from NuGet). Upon compiling the project I got into the error given below and am not able to bypass this. Any help is welcome.
PS: I am working behind corporate proxy.
