Failed to build node project on windows.

I've downloaded builder tools from your website and tried to build node project. But it failed.

C:\Users\Administrator\Documents\builder-windows>builder.exe init https://github.com/johnpapa/node-hello
panic: assignment to entry in nil map

goroutine 1 [running]:
