Install go with brew, and running the gotour

I think I have found the solution, I should have exported:

export PATH=$PATH:/usr/local/Cellar/go/1.0.2/bin/

Instead of

GOPATH=/usr/local/Cellar/go/1.0.2/src/pkg/code.google.com/p/
export GOPATH

Since thats where 'go get' puts the binaries (I guess). gotour is working:

Btw I based my answer on this post

http://code.google.com/p/go-tour/issues/detail?id=39 where they talk about exporting:

/usr/local/Cellar/go/1.0.2/src/pkg/code.google.com/p/

And the getting started page from go: http://golang.org/doc/install where they say you have to export:

export PATH=$PATH:/usr/local/go/bin

Installing go 1.4 with homebrew on OSX:

1) Create Directories

mkdir $HOME/Go
mkdir -p $HOME/Go/src/github.com/user

2) Setup your paths

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

3) Install Go

brew install go

4) "go get" the basics

go get golang.org/x/tools/cmd/godoc

5) Start here: https://golang.org/doc/code.html at "your first program"

Following a mix of answers above, this is what worked for me on OSX 10.12 (Sierra) and Go v1.7.1 using Homebrew:

I added this from Kosh's answer to my .zshrc or .bashrc:

# Go development
export GOPATH="${HOME}/.go"
export GOROOT="$(brew --prefix golang)/libexec"
export PATH="$PATH:${GOPATH}/bin:${GOROOT}/bin"

test -d "${GOPATH}" || mkdir "${GOPATH}"
test -d "${GOPATH}/src/github.com" || mkdir -p "${GOPATH}/src/github.com"

Then in a new terminal window/tab:

$ brew install go

==> Caveats
As of go 1.2, a valid GOPATH is required to use the `go get` command:
  https://golang.org/doc/code.html#GOPATH

You may wish to add the GOROOT-based install location to your PATH:
  export PATH=$PATH:/usr/local/opt/go/libexec/bin
