Installing Go

Visit the Go downloads page: https://golang.org/dl

Get the URL for the latest version of Go

Download go:

curl -O https://dl.google.com/go/go1.11.2.linux-amd64.tar.gz

Verify checksum:

sha256sum go*.tar.gz

Now you're ready to install Go:

tar xvf go*.tar.gz

sudo chown -R root:root ./go

sudo mv go /usr/local

brew install go
brew upgrade go

Following the successful model of pyenv, you can use goenv to set up and manage various side-by-side versions of Go.

Edit your .profile to make the following changes to your environment variables:

GOROOT - (by default, this is /usr/local, not necessary to change) the location of your Go tree
GOPATH - this is a list of paths in which Go code, packages, objects, and executables are stored
PATH - update PATH to include the binary folder of both GOROOT and GOPATH

For example, if Go were installed to the home directory in go/ and work/, these lines would be added to the user's .profile file:

export GOROOT=$HOME/go
export GOPATH=$HOME/work
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
