Installation

Before trying any of these examples make sure to have the Go binary installed on your platform.

OSX:

# Install Homebrew

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

# Install Go

brew install go

Linux:

# Move into $HOME directory
cd ~

# Download the binary for your distribution
curl -O https://dl.google.com/go/go1.12.linux-amd64.tar.gz

# Verify that the downloaded binary is not corrupted. Check if the hash matches the one from downloads page
sha256sum go1.12.linux-amd64.tar.gz

# Extract the binary
tar xvf go1.12.linux-amd64.tar.gz

# Make root user the owner of Go workspace
sudo chown -R root:root ./go

# Move go directory to a standard location
sudo mv go /usr/local

Golang Installation

For downloading Go binary for your platform checkout

Golang Downloads

To check if you installed Go successfully type:

# Displays installed Go version
go version

# Displays all environment variables defined by Go
go env

Docker:

docker run -it golang:1.11

Set $GOPATH variable

sudo nano ~/.profile

# Linux
export GOPATH=/usr/local/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:/$GOBIN

# OSX
export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:/$GOBIN

# Save File

# Restart shell configuration
source ~/.profile

Other Go tools

You can also install other Go tools which will help you have a more productive development process

• Go Tools
• Go Lint
• Go Imports

Go Tools

go get -u golang.org/x/tools/...

Go Lint

go get -u golang.org/x/lint/golint

Go Imports
