Go软件包安装问题：没有安装位置

go install: no install location for _/home/vagrant/packer/builder/amazon/common

I've tried adding a few of the above directories to my GOPATH, but still get all the same errors above.

$ echo $GOPATH 
/home/vagrant/packer:/home/vagrant/packer/builder/amazon/chroot

GOPATH does not work like you assume: It is not a list of paths to look for your code you are trying to build but a path to your Go workspace. Please read http://golang.org/doc/code.html#Organization first. Your GOPATH must contain src, bin and pkg directories, otherwise it is not a workspace.

What the error message is trying to tell you: There is no pkg directory under your GOPATH, so the go tool cannot install what it is trying to build.
