Prerequisites: Installing and Setting Up Termux

First, you need to get Termux. For the best experience and latest updates, install Termux from the official F-Droid store, as the version on the Google Play Store is often outdated.

1. Download Termux from F-Droid.
2. Open the app and run your first command to update all packages:
   bash apt update && apt upgrade -y

Step 1: Install PHP and Required Dependencies

Before we can install Composer, we need a PHP environment. Termux makes this simple with its package manager.

Run the following command to install PHP, CURL (to download Composer), and other essential extensions:

pkg install php curl openssl php-apache php-sodium -y

The -y flag automatically confirms the installation.

Step 2: Download and Install Composer in Termux

With PHP in place, we can now use its built-in method to download and run the Composer installer script securely.

Run this single command. It fetches the installer and places the composer executable directly into your Termux $PATH:

curl -sS https://getcomposer.org/installer | php -- --install-dir=/data/data/com.termux/files/usr/bin --filename=composer

• curl -sS: Silently downloads the installer script.
• php -- --install-dir=...: Tells the PHP interpreter to run the script and save the output as composer in the correct bin directory.

Step 3: Verify the Installation

The most crucial step! Let’s confirm that Composer was installed correctly. Check the version:

composer --version

If successful, you’ll see an output like: Composer version 2.x.x 2023-... This means you have successfully installed Composer in Termux.

Step 4: Troubleshooting Common Issues (Sodium Error Fix)

A common error when running Composer commands later is related to the sodium extension. Here’s how to proactively fix it:

1. First, verify that the PHP sodium extension is installed and active: php -i | grep sodium You should see a line confirming it’s enabled.
2. If you encounter a “required extension sodium is missing” error when installing a package (e.g., for Firebase), you can require the package with a flag that ignores platform requirements for this initial install:
   bash composer require kreait/firebase-php --ignore-platform-req=ext-sodium
   This often resolves the initial conflict.

(Optional) Step 5: Configuring a GitHub Personal Access Token

If you plan to use Composer with private repositories or have high usage, you may hit GitHub API rate limits. To avoid this, you can set up a Personal Access Token.

1. Create a token on GitHub.com (classic) with the repo scope.
2. In Termux, create or edit the Composer global config file:
   bash nano ~/.composer/composer.json
3. Add the following configuration, replacing YOUR_TOKEN_HERE with your actual token:
   json { "config": { "github-oauth": { "github.com": "YOUR_TOKEN_HERE" } } }
4. Save the file (Ctrl+X, then Y, then Enter).

Conclusion: You’re Ready to Develop!

Congratulations! You have successfully learned how to install Composer in Termux. You now have a powerful PHP development setup right in your pocket. You can now create new PHP projects, manage dependencies with composer require, and work on your code from anywhere.
