Golang setup

This is a simple article to show you how to setup you Go enviroment properly, specailly if you are a homebrew user

If you installed Go, using home brew. brew install golang, you likely will have a slightly different setup than those installing Go from the original installation. To map the actual GOROOT just use brew --prefix golang and then of course the libexec directory

Export bin, for both Goroot and Gopath.

# go working directory in my account and the bin
export GOPATH="/Users/mohamedallam/go"
export PATH="$PATH:$GOPATH/bin"

# You can instead # export GOPATH=/Users/$USER/go
# Or you can choose another directory  GOPATH=/Users/$USER/anotherDirectory

# go root directory (brew) with the bin
export GOROOT="$(brew --prefix golang)/libexec"
export PATH="$PATH:$GOROOT/bin"

Now you chould be able to

go version
go version go1.19 darwin/amd64
