cc-pika-install

One-command installer for Claude Code with automatic custom configuration.

Before You Start

You need Node.js and Git installed on your computer first. If you've never installed them before, follow the full walkthrough in PREREQUISITES.md (5 minutes, beginner-friendly with screenshots-worth-of-detail).

Quick check — open a terminal (Command Prompt on Windows, Terminal on Mac) and run:

node -v
git --version

If both commands print a version number (e.g. v20.11.1 and git version 2.43.0), you're ready. If either says "not recognized" or "command not found", go to PREREQUISITES.md first.

TL;DR for those in a hurry:

1. Install Node.js LTS from https://nodejs.org (just click Next-Next-Finish)
2. Install Git from https://git-scm.com/downloads (same — Next-Next-Finish)
3. Restart your terminal, then continue to Quick Start below.

Quick Start

Make sure you've completed Before You Start — node -v and git --version should both work.

Recommended (Node.js + Git already installed)

npx cc-pika-install

On Linux/macOS, you may need sudo:

sudo npx cc-pika-install

Fallback (auto-installs Node.js + Git if missing)

Use this if you skipped the prerequisites and want the setup script to install everything for you.

Linux/macOS:

curl -fsSL https://raw.githubusercontent.com/pikachuladiva-rgb/cc-pika-install/main/setup.sh | bash

Windows: Open PowerShell as Administrator and run:

Invoke-WebRequest -Uri 'https://raw.githubusercontent.com/pikachuladiva-rgb/cc-pika-install/main/setup.bat' -OutFile "$env:TEMP\setup.bat"; Start-Process "$env:TEMP\setup.bat" -Verb RunAs

Note: the fallback path is less reliable on macOS (it requires Homebrew) and may need a terminal restart on Windows. The manual prerequisites route is more robust.

What It Does

This installer automates the entire Claude Code setup process:

1. ✅ Installs Claude Code globally via npm
2. ✅ Prompts you for your API Base URL
3. ✅ Prompts you for your API Key
4. ✅ Creates ~/.claude/settings.json with your configuration
5. ✅ Configures permissions and skips onboarding

After installation completes, simply run claude to start using Claude Code.

Requirements

• Node.js 18 or newer - Download here
• npm (comes with Node.js)
• sudo access (on Linux/macOS for global installation)

Step-by-Step Usage

1. Run the installer:

   npx cc-pika-install

2. Enter your API Base URL when prompted:

   Enter API Base URL: https://your-api-endpoint.com

3. Enter your API Key when prompted:

   Enter your API key: sk-your-api-key-here

4. Wait for installation to complete:

   Installing Claude Code via npm...
   Configuring Claude Code...
   Configuration complete! Claude Code is ready to use.

5. Start using Claude Code:

   claude

Configuration

The installer creates ~/.claude/settings.json with:

• Custom API endpoint (ANTHROPIC_BASE_URL)
• Your API authentication token
• Bypass permissions mode enabled
• Onboarding steps skipped

Uninstallation

One-liner (recommended):

npx cc-pika-uninstall

On Linux/macOS you may need sudo:

sudo npx cc-pika-uninstall

This removes Claude Code (@anthropic-ai/claude-code) and the ~/.claude config directory. Node.js and Git are kept.

Troubleshooting

Permission denied error:

• Use sudo npx cc-pika-install on Linux/macOS
• Run as Administrator on Windows

Node.js not found:

• Install Node.js 18+ from https://nodejs.org/
