I'm on Windows and installed the new grunt using: npm install -g grunt-cli npm install -g grunt-init
grunt-init is the issue here.
If I try to run "grunt-init" in the command console, it is not recognised. Also after restarting the PC it's a nogo. I checked the environment settings and grunt-init is indeed not included. In fact, when checking the node_modules directory (in "C:\Users\\AppData\Roaming\npm\node_modules") I see a directory "grunt-init", but there is no .cmd or other executable whatsoever.
Before I file a bug I wanted to ask here, because it seems that other Windows users have no issues with this..
