Panic: No source files found in ./example/hello (./example/hello)

[nestedbytes]

I cloned the repo and ran:

go build -o babygo

and then

./babygo build -o hello ./example/hello

but it gave an error

panic: No source files found in ./example/hello (./example/hello)

goroutine 1 [running]:
......... 

i also tried running

./babygo build -o hello ./example/

and i got

panic: No source files found in /home/shour/go/src/github.com/DQNEO/babygo/src/os (os)

I am using Fedora linux
Thanks,
