Golang setup in Mac OSX with HomeBrew. Set `GOPATH` and `GOROOT` variables in zshell, fish or bash.

.bashrc

# Set variables in .bashrc file

# don't forget to change your path correctly!

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

.zshrc

# Set variables in .zshrc file

# don't forget to set path correctly!

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

config.fish

# Set variables in config.fish file

# don't forget to set path correctly!

# GOLANG configurations
set -x GOPATH $HOME/golang
set -x GOROOT /usr/local/opt/go/libexec
set PATH $GOPATH/bin $GOROOT/bin $PATH

install.sh

echo "Please enter your golang path (ex: $HOME/golang) :"
read gopath

echo "Please enter your github username (ex: vsouza) :"
read user


mkdir $gopath
mkdir -p $gopath/src/github.com/$user

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

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew update
brew install go
brew install git

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

@javaducky thanks man - super helpful!

better get the prefix via brew --prefix

Anyone on Apple silicon will need to instead use the updated prefix for Homebrew, i.e. /opt/homebrew instead of /usr/local. The remainder of the paths will be the same.

The .zshrc example would therefore be:

# Set variables in .zshrc file

# don't forget to set path correctly!

export GOPATH=$HOME/golang
export GOROOT=/opt/homebrew/opt/go/libexec
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOROOT/bin

👍🏼

yeah I used go env first, and then used this as a guide to modify my .zshrc, trusting that go env was correct. Annoyingly GOBIN was '' though, so I'm not 100% sure the stability of homebrew golang recipe.
