When I attempt to create a new blank Cordova app in Visual Studio 2013 with the Multi Device Hybrid Apps CTP I get the following error message.
I had the same exact error as Levi and it was because a few directories were not created in the node_modules directory during installation. Re-installing node and/or the entire CTP2.0, restarting, clapping my hands, screaming, etc would not fix this in my environment. On another PC, this worked fine. To fix this problem:
C:\Program Files (x86)\Microsoft Visual Studio
12.0\Common7\IDE\Extensions\ and search for "vs-mda". You should find both a "vs-mda" and "vs-mda-targets" folder. (Make a recursively search, you won't find the folders exactly in "Extensions", there are inside of a random-named folder)%appdata%\npm\node_modules\Now, once this worked, I still got an error about the Git CLI missing. That was solved with this answer.
I hope this helps!
