$ gvm version
	Go Version Manager v1.0.22 installed at /home/pi/.gvm

install Go

gvmは全ての基点に1.4を利用しているようで、他のversionを利用するつもりでもまずは1.4をinstallしなければならない

install go1.4

$ gvm install go1.4
	Installing go1.4...
	 * Compiling...
	go1.4 successfully installed!

$ gvm list
	gvm gos (installed)
	   go1.4

$ gvm use go1.4
	Now using version go1.4
$ gvm list
	gvm gos (installed)
	=> go1.4

install go1.5

他のversionのinstallの確認として、stableの最新版である1.7.5をinstallしてみる

### install
$ echo $GOROOT
	/home/pi/.gvm/gos/go1.4

$ export GOROOT_BOOTSTRAP=$GOROOT

$ gvm install go1.7.5
	Installing go1.7.5...
	 * Compiling...
	go1.7.5 successfully installed!

$ gvm use go1.7.5 --default
	Now using version go1.7.5

$ gvm list
	gvm gos (installed)
	   go1.4
	=> go1.7.5

### confirm
$ go version
	go version go1.7.5 linux/arm
