Cannot install on macOS

[agross]

I'm not a Go user so I don't know exactly what this error means:

$ go get github.com/zach-klippenstein/adbfs
package github.com/zach-klippenstein/goadb/util: cannot find package "github.com/zach-klippenstein/goadb/util" in any of:
	/usr/local/Cellar/go/1.14.4/libexec/src/github.com/zach-klippenstein/goadb/util (from $GOROOT)
	/Users/agross/go/src/github.com/zach-klippenstein/goadb/util (from $GOPATH)

/Users/agross/go/src/github.com/zach-klippenstein/goadb/util.go exists, but it seems that it is not considered.

$ go version
go version go1.14.4 darwin/amd64

Same here, on Ubuntu 18.04.
