How to install Composer on Windows?

Check PHP installation by running php -v in Command Prompt and ensure PHP is in PATH. 2. Download the Composer-Setup.exe installer from getcomposer.org, run it, follow the wizard, and allow system-wide installation. 3. Verify installation by running composer --version in a new Command Prompt to confirm successful setup. 4. Troubleshoot issues: re-run installer if "composer is not recognized", verify PHP path if PHP is not detected, or disable antivirus if it blocks the installer. Composer is now ready for managing PHP dependencies on Windows.

Installing Composer on Windows is straightforward if you follow the right steps. Composer is a dependency manager for PHP, and having it set up correctly makes working with PHP projects much easier.

1. Check Your PHP Installation

Before installing Composer, make sure PHP is installed and available from the command line.

• Open Command Prompt (cmd) and run:

  php -v

• You should see the PHP version displayed. If not, you need to install PHP first or ensure it's added to your system's PATH.

Tip: If you're using XAMPP, WAMP, or Laravel's PHP development server like Laravel Valet, PHP is likely already installed. Just confirm it's accessible globally.

2. Download and Run the Composer Installer

The easiest way to install Composer on Windows is using the official installer.

• Go to //m.sbmmt.com/link/7bcab4942f4f7e074eb4f7b4ecdf4f61
• Download the Windows Installer (.exe file)
• Run the downloaded file (e.g., Composer-Setup.exe)
• Follow the installation wizard:
  • It will automatically detect your PHP installation (if in PATH)
  • Choose the PHP executable if prompted (usually php.exe from your PHP directory)
  • Allow it to install system-wide if you want to use Composer from any location

Note: During installation, the setup may ask if you want to use proxy settings — leave them blank unless you're behind a corporate firewall.

3. Verify the Installation

After installation completes, open a new Command Prompt window (important — to refresh environment variables) and type:

composer

You should see a list of available Composer commands. If so, it’s installed correctly!

Try testing it with a basic command:

composer --version

This should output something like:

Composer version 2.7.0 2024-04-05 08:47:30

4. Troubleshooting Common Issues

• "composer is not recognized" error:
  This means Composer wasn't added to your PATH. Re-run the installer and make sure to allow it to modify system environment variables.

• PHP not found during setup:
  Double-check your PHP installation path (e.g., C:\php or C:\xampp\php) and ensure php.exe exists there. Add the folder to your system PATH manually if needed.

• Antivirus blocking the installer:
  Some antivirus tools flag the Composer installer. Temporarily disable it or allow the download if you trust the source.

That’s it — Composer should now be ready to use on your Windows machine. You can start managing PHP dependencies with composer.json in your projects.
