Installing Go

Windows

Download and run the installer found at http://golang.org/doc/install

OS X

For simplicity down the line, it is recommended to install Go via brew rather than installing via http://golang.org/doc/install

Install brew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

Install Go:

brew update brew install go

You need a go directory to place your Go apps, so create it. You can call it whatever your want, most people choose to call it 'Go'

mkdir ~/go;

Now set the GOPATH to the directory you just created. GOPATH is where Go will look for your Go apps

export GOPATH=$HOME/go

This will only work for the duration of your session, so save it to your bash profile

echo GOPATH=$GOPATH >> ~/.bash_profile

Ubuntu

Download the latest distribution

curl -O https://go.googlecode.com/files/go1.2.linux-amd64.tar.gz

Unpack it to the /usr/local (might require sudo)

tar -C /usr/local -xzf go1.2.linux-amd64.tar.gz

export PATH=$PATH:/usr/local/go/bin mkdir ~/go; export GOPATH=$HOME/go
