Getting Claude Code running on your system doesn’t have to be complicated. We at Yanina Travel know that developers need clear, practical guidance to install Claude Code quickly and start building right away.
This guide walks you through every step-from checking your system requirements to running your first script. You’ll have Claude Code up and working in minutes.
What You Need to Run Claude Code
Claude Code runs on modern operating systems with modest hardware requirements. macOS 13.0 and later, Windows 10 1809 and later, and Linux distributions like Ubuntu 20.04, Debian 10, and Alpine Linux 3.19 all support Claude Code without issues. You’ll need a minimum of 4 GB RAM, though 8 GB works better if you run multiple applications alongside Claude Code.
Internet access is mandatory since Claude Code communicates with Anthropic’s servers for processing. Your terminal must support Bash or Zsh, which come standard on macOS and most Linux systems. Windows users can run Claude Code natively through Git Bash or Windows Subsystem for Linux 2, with WSL 2 offering better sandboxing than WSL 1.
Hardware That Works
Most developers don’t need expensive hardware. An M4 Air MacBook with 16 GB RAM and 512 GB storage handles Claude Code smoothly for typical development work. If you work with larger codebases or run Docker containers simultaneously, an M4 Pro MacBook with 24 GB RAM gives you more breathing room. Windows users should try similar specifications-16 GB RAM as a baseline, preferably with an SSD for faster file operations. Claude Code itself is lightweight; the limiting factor is usually your IDE and any local services you run alongside it. Node.js 18 or higher is only required if you use the deprecated npm installation method, which you should avoid.
Dependencies You Need to Install
Ripgrep comes bundled with most Claude Code installations automatically, so you don’t need to install it separately unless you’re on Alpine Linux or another musl-based distribution. On these systems, you’ll need to install libgcc, libstdc++, and ripgrep manually. Most developers on standard macOS, Windows, or Ubuntu systems skip this step entirely since the bundled version handles everything. The installation process detects your system and includes the right tools without extra configuration.
With your system checked and hardware confirmed, you’re ready to move forward with the actual installation process.
Getting Claude Code Running
The native installation method is your best choice, and it takes under two minutes on most systems. Open your terminal and run curl -fsSL https://claude.ai/install.sh | bash on macOS, Linux, or Windows Subsystem for Linux. Windows users without WSL can download the PowerShell installer with install.ps1 or the CMD installer with install.cmd from the official Claude Code repository, then execute it in your terminal. Native installations update automatically in the background, so you stay current without manual intervention. This matters because Claude Code releases security patches and performance improvements regularly, and missing those updates means working with outdated capabilities. Homebrew and WinGet installations skip the auto-update feature entirely, requiring you to manually run brew upgrade claude-code or winget upgrade Anthropic.ClaudeCode every few weeks.
If you prefer a package manager, accept that manual updates become your responsibility. Docker offers another path for teams managing Claude Code across multiple machines or running it in isolated environments, but it adds complexity that most individual developers don’t need. The overhead of containerization only makes sense when you standardize deployments across a team or run Claude Code alongside incompatible services.
Choose Your Installation Method
Native installation remains the fastest and most reliable approach for individual developers. The curl command handles everything automatically, detecting your operating system and installing the correct binaries without extra steps. Windows users who cannot use WSL should download the appropriate installer script (PowerShell or CMD) and run it directly in their terminal. Package managers like Homebrew and WinGet work well if you already use them for other tools, though you’ll need to monitor updates manually. Docker installations suit teams that need standardized environments across multiple developers or CI/CD pipelines, but the added complexity rarely justifies itself for solo projects.
Authenticate and Set Up Your Account
Start Claude Code by running claude in your project directory, and you’ll be prompted to log in on first use. Your authentication options depend on your subscription: Claude Pro or Max users log in through their Claude.ai account, Claude Console users authenticate with API credentials and pre-paid credits, and teams on Claude for Teams or Enterprise use centralized organization accounts. Claude Code creates a workspace automatically in the Claude Console for cost tracking, so you see exactly how many tokens you consume and what your usage costs. Switching between accounts later uses the /login command, which disconnects your current session and prompts you to authenticate with different credentials. Teams should use Claude for Teams rather than individual Pro subscriptions, since it enables centralized billing and prevents the chaos of tracking expenses across multiple personal accounts. Enterprise deployments can configure cloud provider integrations with Amazon Bedrock, Google Vertex AI, or Microsoft Foundry, which requires setting up environment variables and credentials specific to each provider.
Secure Your Credentials
After authentication completes, Claude Code stores your credentials securely on macOS Keychain in encrypted form, covering API keys and OAuth tokens. Credentials refresh automatically by default, and you can customize this interval with the CLAUDE_CODE_API_KEY_HELPER_TTL_MS environment variable if your setup requires different timing. This automatic refresh prevents authentication failures during long coding sessions and keeps your access tokens valid without interruption. Your credentials remain local to your machine, so switching between computers requires logging in again on each system. Teams managing multiple developers should configure role-based access control to limit what Claude Code can access and do within your environment, restricting permissions to specific subdirectories or services as needed. With authentication complete and credentials secured, you’re ready to create your first project and test Claude Code with a practical example.
Run Your First Claude Code Project
Open your terminal, navigate to an empty directory, and type claude to start your first session. Claude Code displays a welcome screen showing your session information, recent conversations, and any available updates. This initial launch creates your workspace and confirms that authentication is working correctly. Ask Claude a straightforward question about what you want to build-something like “create a Python script that prints hello world to test the setup.” Claude analyzes your project directory, locates the right file to edit, and proposes the changes it plans to make. You must approve each modification before Claude applies it, giving you full control over what gets written to your codebase. This approval step prevents accidental overwrites and trains you to understand exactly what Claude is doing at each stage. After you approve, Claude creates the hello.py file with a simple function that outputs hello world.
Run python3 hello.py in your terminal and you’ll see the output immediately, confirming that Claude Code can write, save, and execute code successfully. This first test typically takes under three minutes from start to finish and proves your installation is complete and functional.
Set Up Git as Your Safety Net
Once hello world works, initialize Git in your project directory since Claude Code treats Git as a permanent safety net for all changes. Run git init to initialize a repository, then configure your identity with git config user.name and git config user.email using your actual name and email address. These settings matter because every commit Claude Code makes will be attributed to your account. Add your hello.py file to Git with git add . and commit it with git commit -m “initial commit” to create your first checkpoint. From this point forward, commit frequently after each feature or fix-don’t wait until you’ve made dozens of changes. Developers who commit often can roll back specific changes without losing hours of work, while those who commit rarely end up reverting entire sessions when something breaks.
Leverage Claude Code’s Git integration
Claude Code integrates directly with Git, so you can ask Claude to commit changes with descriptive messages, view file changes before committing, or even resolve merge conflicts conversationally. The tool performs the Git operations for you, but you maintain full visibility and control over what gets committed. This integration means you never need to leave your Claude Code session to manage version control-everything happens within the same conversation. Ask Claude what files changed, and it shows you the diff. Ask Claude to commit, and it proposes a message based on the work you’ve done. This workflow keeps you focused on building rather than switching between tools.
Troubleshoot Authentication and Connection Issues
The most frequent error during first use is authentication timeouts when Claude Code tries to connect to Anthropic’s servers. If you see a connection error, verify that your internet connection is stable and that you’re not behind a corporate firewall blocking outbound HTTPS requests. Some enterprise networks require proxy configuration, which you can set through environment variables if needed. Another common issue is permission errors on Linux systems when Claude Code tries to write files to directories you don’t own. Fix this by running the installation commands in a directory where your user account has full write permissions, not in system directories or restricted folders.
Resolve Platform-Specific Setup Problems
Windows users occasionally encounter issues with Git Bash not being recognized in the terminal, which you solve by ensuring Git for Windows is installed before running Claude Code. Run claude doctor after installation to verify your setup type, version, and basic system configuration-this command catches most problems immediately and suggests fixes. If you still encounter errors after running doctor, check the official troubleshooting guide, which covers edge cases and advanced configurations. The vast majority of installation problems resolve within minutes once you identify whether the issue is authentication, permissions, or dependencies.
Final Thoughts
You now have Claude Code installed and running on your system, with your first project committed to Git and ready for expansion. Move forward by applying Claude Code to real work rather than toy examples-ask it to refactor existing code, write tests for functions you’ve built, or add features to applications you’re actively developing. These practical tasks teach you how Claude Code thinks and where it excels far better than hypothetical exercises, and committing frequently after each change protects your progress.
