Composer is a popular dependency management tool for PHP, created mainly to facilitate installation and updates for project dependencies.
Also, it acts as a package manager for PHP.
It is used to gracefully manage all the packages and dependencies for this programming language hence offloading the developers from the responsibility of doing this manually.
In this context, we shall look into how we can install Composer on a Linux Mint system.
How to install Composer on Linux Mint ?
Before proceeding with this installation procedure, you need to have "PHP" installed on your Linux system with "sudo" privileges.
Then follow the steps given below.
1. Download Composer from its Official Website
First, you need to download Composer from its official website by executing the following command:
$ wget https://getcomposer.org/composer.phar
You can also mention the exact version of Composer in this command that you want to download.
However, running this command as it is will ensure that you download the latest available version of Composer on your system.
2. Make the Downloaded Composer File Executable
Now, you need to make the downloaded file executable with the command shown below:
$ chmod +x ./composer.phar
This command will not render any messages on your terminal if it is executed without any errors.
3. Change the Path of the Executable Composer File to make it easily accessible
After performing the above-mentioned step, you need to move your executable Composer file to the /usr/bin/composer directory for making it easily accessible.
You can do this by executing the following command:
$ sudo mv ./composer.phar /usr/bin/composer
You should run the above-mentioned command as it is because omitting the "sudo" keyword from this command will not let you change the path of the executable Composer file.
Also, if this command will execute without any errors, then it will not produce any messages on your terminal.
4. Verify the Installation of Composer on your Linux System
Finally, you can verify the successful installation of Composer on your Linux system by checking its location with the command shown below:
$ which composer
The location of Composer on our Linux system will be displayed in the terminal which indicates that Composer has been successfully installed on our Linux system.
How to Uninstall Composer from Linux Mint ?
You can easily uninstall Composer from your Linux machine by first executing the command shown below:
$ sudo apt-get purge composer
After executing this command, you can run the following command in your terminal to free up more space on your Linux system:
$ sudo apt-get autoremove
