Installing the Latest Version of Composer on Ubuntu
Composer is a widely-used dependency manager for PHP that simplifies managing libraries and dependencies for your projects. In this guide, we will walk you through the process of installing the latest version of Composer on Ubuntu.
Update Your System
First, open your terminal and update your package list to ensure you have the latest information on available packages
1. sudo apt update
2. sudo apt upgrade
Install Required Dependencies
Composer requires certain PHP extensions and utilities to function properly. Install the necessary packages by running the following command:
1. sudo apt install curl php-cli php-mbstring git unzip
Download Composer Installer
Next, you’ll need to download the Composer installer script. Run the following command:
1. curl -sS https://getcomposer.org/installer -o composer-setup.php
Verify the Installer
Before running the installer, it’s a good practice to verify its integrity. You can do this by checking the SHA-384 hash. First, get the latest installer hash:
1. HASH="$(curl -sS https://composer.github.io/installer.sig)"
Then, verify the downloaded installer:
1. if [ "$(openssl dgst -sha384 -binary composer-setup.php | openssl base64)" = "$HASH" ]; then
2. echo 'Installer verified'
3. else
4. echo 'Installer corrupt'
5. unlink composer-setup.php
6. exit 1
7. fi
If the installer is verified, you will see "Installer verified" in the output.
Install Composer
Now you can install Composer globally on your system. Run the following command:
1. sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer
This command installs Composer in the /usr/local/bin directory and names it composer, making it accessible from anywhere on your system.
Verify Composer Installation
To verify that Composer was installed successfully, run the command:
1. composer -v
By following these steps, you have successfully installed the latest version of Composer on your Ubuntu system. Composer is an essential tool for PHP developers, allowing you to manage your project dependencies effectively. With Composer set up, you can streamline your PHP development process and focus on building robust applications.
