Como instalar a linguagem de programação Go (Golang)

Renato Cruz

A Go (também conhecida como Golang) é uma linguagem moderna, simples e extremamente eficiente, criada pelo Google. Muito utilizada para desenvolvimento de APIs, microsserviços, ferramentas de linha de comando e sistemas distribuídos, o Go se destaca pela sua performance e facilidade de uso.

Neste guia, você vai aprender como instalar o Go nos principais sistemas operacionais macOS, Linux e Windows, utilizando tanto métodos oficiais quanto gerenciadores de pacotes.

Ao final, também verá como iniciar seu primeiro projeto e compilar aplicações, incluindo cross-compilation.


macOS

Site oficial

Acesse o site oficial, faça o download do arquivo *.pkg e dê dois cliques para iniciar a instalação.

Homebrew (recomendado)

brew install go

Enter fullscreen mode Exit fullscreen mode

Caso ainda não tenha o Homebrew instalado, veja este guia: https://dev.to/natorsc/como-instalar-o-gerenciador-de-pacotes-homebrew-no-macos-1mfm


🐧 Linux

Site oficial

Acesse o site oficial e faça o download do arquivo *.tar.gz.

  1. Remova qualquer instalação anterior do Go e extraia o novo pacote:
sudo rm -rf /usr/local/go && \
sudo tar -C /usr/local -xzf go1.26.2.linux-amd64.tar.gz

Enter fullscreen mode Exit fullscreen mode

Não descompacte o arquivo dentro de um diretório /usr/local/go já existente, isso pode causar erros na instalação.

  1. Adicione o Go ao PATH:
export PATH=$PATH:/usr/local/go/bin

Enter fullscreen mode Exit fullscreen mode

Adicione essa linha ao arquivo $HOME/.profile (usuário) ou /etc/profile (sistema).

Para aplicar:

source $HOME/.profile

Enter fullscreen mode Exit fullscreen mode

  1. Verifique a instalação:
go version

Enter fullscreen mode Exit fullscreen mode


Repositórios (mais prático)

As versões disponíveis podem estar desatualizadas em relação ao site oficial.

Debian/Ubuntu

sudo apt install golang gcc

Enter fullscreen mode Exit fullscreen mode

Fedora

sudo dnf install golang golang-misc gcc

Enter fullscreen mode Exit fullscreen mode

Arch Linux

sudo pacman -S go

Enter fullscreen mode Exit fullscreen mode

Solus

sudo eopkg it -c golang system.devel

Enter fullscreen mode Exit fullscreen mode

openSUSE

sudo zypper install go gcc

Enter fullscreen mode Exit fullscreen mode

Void Linux

sudo xbps-install -S go base-devel

Enter fullscreen mode Exit fullscreen mode

Alpine Linux

sudo apk add go gcc

Enter fullscreen mode Exit fullscreen mode


Microsoft Windows

Site oficial

Baixe o instalador *.msi e execute com duplo clique.

MSYS2

pacman -Syu

Enter fullscreen mode Exit fullscreen mode

pacman -S git mingw-w64-x86_64-toolchain mingw-w64-x86_64-go

Enter fullscreen mode Exit fullscreen mode

Adicione ao PATH:

echo "export PATH=\$PATH:~/Go/bin" >> ~/.bashrc

Enter fullscreen mode Exit fullscreen mode

Winget

winget install --id=GoLang.Go -e

Enter fullscreen mode Exit fullscreen mode


Como iniciar um projeto em Go

Crie uma pasta e inicialize o módulo:

go mod init nome-do-projeto

Enter fullscreen mode Exit fullscreen mode

Crie um arquivo main.go:

package main

import "fmt"

func main() {
    fmt.Println("Hello, World!")
}

Enter fullscreen mode Exit fullscreen mode

Execute:

go run main.go

Enter fullscreen mode Exit fullscreen mode

Compile:

go build main.go

Enter fullscreen mode Exit fullscreen mode

Será gerado um binário para o sistema operacional atual.


Cross-compilation

Para gerar binários para outros sistemas:

GOOS=darwin GOARCH=arm64 go build main.go

Enter fullscreen mode Exit fullscreen mode

Esse exemplo gera um binário para macOS com arquitetura ARM (Apple Silicon – M1, M2, etc).

Você pode alterar os valores de GOOS e GOARCH conforme necessário:
