This is because mime (and other modules) in package.json have ">=" version options... and the API for mime changed between v1 and v2.

(And this is why you should never use ">=" in package.json :-/)

pardon, forget to add the detail step to produce the error above :
npm install punch
./node_modules/.bin/punch setup mysite
cd mysite
../node_modules/.bin/punch s
open http://localhost:9009
