issue to run "make dev"

[shanegu]

I'm using ubuntu and whenever I ran "make dev", following errors show up:
trap 'kill %1' SIGINT
trap: SIGINT: bad trap
Makefile:3: recipe for target 'dev' failed
make: *** [dev] Error 1

but I can run individual command:
trap 'kill %1' SIGINT
then run
npm run watch & sam local start-api
