GO wants to import the package from $GOPATH env at first. If go can't find the package, an error is raised.
Add our project directory into $GOPATH env.
debug@ulab:/tmp/test$ go run main.go
main.go:3:8: cannot find package "mylib" in any of:
/home/debug/.golang/go/src/mylib (from $GOROOT)
/home/debug/.golang/gopath/src/mylib (from $GOPATH)
$ tree
.
├── main.go
├── src
│ └── hello
│ └── hello.go
└── start.sh
2 directories, 3 files
$ cat start.sh
#!/bin/sh
GOPATH="$(pwd):$(go env GOPATH)"
go run main.go
$ ./start.sh
