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 goLinux:
# 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/localFor more details regarding Go installation check out
For downloading Go binary for your platform checkout
To check if you installed Go successfully type:
# Displays installed Go version
go version
# Displays all environment variables defined by Go
go envDocker:
docker run -it golang:1.11Set $GOPATH variable
sudo nano ~/.profile
# Linux
export GOPATH=/usr/local/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:/$GOBIN
# OSX
export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:/$GOBIN
# Save File
# Restart shell configuration
