去工具：没有这样的工具“旅行”

Question

I'm trying out Go for the first time. I was following these docs and wanted to run the go tour locally, but I haven't figured out how to get it to work.

Where is the tool "tour" supposed to be found?
I'm on OSX 10.11.3, and I installed Go via Homebrew
my Go entries in .zshrc

export GOPATH=$HOME/code/Go
export GOROOT=/usr/local/opt/go/libexec
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOROOT/bin

Answer 1

tour is not installed by default with an installation of go. You need to go get it:

go get golang.org/x/tour/gotour
