the command works just fine on my setup but when issuing the command with grunt it gives me a strange error

gistfile1.txt

task :m do
	sh "METEOR=Y MONGO_URL=mongodb://localhost:27017/statscf meteor --port 3010"
	exit
end


and when i do `rake m` I get:

METEOR=Y MONGO_URL=mongodb://localhost:27017/statscf meteor --port 3010
rake aborted!
Command failed with status (127): [METEOR=Y MONGO_URL=mongodb://localhost:270...]

Tasks: TOP => m
(See full trace by running task with --trace)


and with --trace:
** Invoke m (first_time)
** Execute m

rake aborted!
