Install OpenCode

Prasyarat

Node.js 18+ (sudah include npm)
Terminal (PowerShell Windows, Terminal Mac/Linux)
Internet

Cek Node.js

bash

node --version
npm --version

Harus keluar versi (contoh: v20.10.0 dan 10.2.3).

Belum Punya Node.js? Install LTS:

Windows (Pilih 1)

powershell

# Opsi 1: Winget (cepat)
winget install OpenJS.NodeJS.LTS

# Opsi 2: Chocolatey
choco install nodejs-lts

# Opsi 3: Manual - download di nodejs.org → pilih LTS → next-next-finish

macOS

bash

# Homebrew (recommended)
brew install node@20

# Atau manual download di nodejs.org

Linux (Ubuntu/Debian)

bash

# NodeSource (versi terbaru LTS)
curl -fsSL https://deb.nodesource.com/setup_lts.x | sudo -E bash -
sudo apt-get install -y nodejs

# Atau package manager biasa
sudo apt update && sudo apt install nodejs npm

Restart terminal setelah install, lalu cek node --version.

Install OpenCode

bash

npm install -g opencode-ai

Tunggu beberapa menit.

Verifikasi

bash

opencode --version

Keluar versi = sukses.

Windows error execution policy? Jalankan PowerShell as Administrator:
powershell
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
