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

👍 thanks for the help.

For those like myself unfamiliar with go, you might have to run your go get commands with -d tag if you're running into the issue can't load package: package .: no buildable Go source files in while trying to install your package (Stack Overflow Reference).

Thanks for your help.

I get the following error after inserting path and GitHub username.

mkdir: /Users/username/GitHub/Go: File exists /Users/username/Downloads/77e6[...]b8b9c/install.sh: line 26: syntax error: unexpected end of file

Any idea what this means?

I'm getting that error as well.
line 26: syntax error: unexpected end of file

Any ideas?

package golang.org/x/tools/cmd/vet: cannot find package "golang.org/x/tools/cmd/vet" in any of:
/usr/local/opt/go/libexec/src/golang.org/x/tools/cmd/vet (from $GOROOT)
/Users/xavi/golang/src/golang.org/x/tools/cmd/vet (from $GOPATH)

Anyone else with this error?

@mjreed09 and @xavipedrals
try with

command -v brew >/dev/null 2>&1 || { ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"; };

its missing semicolons

Thank you for the help and instructions @vsouza, very useful.

A couple of points based on my experiencing of carrying out these instructions on OSX 10.11.3

1. I could not find .bashrc so I placed the exports inside .bash_profile
2. I already had homebrew and git and when I run the ./install.sh it upgraded homebrew and give error while trying to install git because it was already installed.
3. At the end I got the following

package golang.org/x/tools/cmd/vet: cannot find package "golang.org/x/tools/cmd/vet" in any of: /usr/local/opt/go/libexec/src/golang.org/x/tools/cmd/vet (from $GOROOT) /Users/Raf/workspace/golang/src/golang.org/x/tools/cmd/vet (from $GOPATH)

I checked /users/Raf/workspace/golang/src/golang.org/x/tools/cmd/vet and it exist, so not sure why the error if it already exist.

I tried the go run helloworld.go and I got the result.

Regarding godoc and vet: https://golang.org/doc/go1.2#go_tools_godoc

I didn’t want to manually edit the paths in the .*rc so I added the following to the install.sh:

grep GOPATH ~/.zshrc || sed "s|^export GOPATH=.*|export GOPATH=${gopath}|g" >> ~/.zshrc <<EOF
export GOROOT=/usr/local/opt/go/libexec
export GOPATH=$HOME/golang
export PATH=\$PATH:\$GOPATH/bin
EOF

It’s not perfect but works for me. I only use zsh..maybe someone has time to do like if $SHELL = 'zsh' .. else ..

Great Job! Thank U!

@rmldsky
According to https://golang.org/doc/go1.2#go_tools_godoc :

$ go get code.google.com/p/go.tools/cmd/godoc
package code.google.com/p/go.tools/cmd/godoc: unrecognized import path "code.google.com/p/go.tools/cmd/godoc" (parse https://code.google.com/p/go.tools/cmd/godoc?go-get=1: no go-import meta tags)
$ go get code.google.com/p/go.tools/cmd/vet
package code.google.com/p/go.tools/cmd/vet: unrecognized import path "code.google.com/p/go.tools/cmd/vet" (parse https://code.google.com/p/go.tools/cmd/vet?go-get=1: no go-import meta tags)

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

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.
