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

BTW, we should set only $GOPATH and $PATH (for brew at least), $GOROOT integrated inside go's binary.

# cat ~/.bashrc
export GOPATH=$HOME/golang
export PATH=$PATH:/usr/local/opt/go/libexec/bin
# ls -all /usr/local/opt/go

Found that you don't need to install godoc

Why is brew install mercurial installed?

@Gerst20051 Was the old golang setup, Isn't necessary anymore.

Thanks a lot for that script.
It can be updated and improved slightly but it is highly required. :-D
I can't understand why there isn't anything like that from the Golang website?
Either MacOS Package and an install script or via Brew and an install script.

Thanks a lot for your work. That was really helpful.

thanks a lot this gist save my life lol

@dagadbm good

Big thank you

Thanks!

Setup for fish users

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

thanks bro

worked for me by changing
export GOPATH=$HOME/golang into export GOPATH=$HOME/go

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

@javaducky OMG, you saved my life!!!

/opt/homebrew instead of /usr/local for M1

I wish I read this at the beginning 😭

@javaducky thanks man - super helpful!

better get the prefix via brew --prefix

👍🏼

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.
