Notice that we immediately write this article to help our audience with this matter. To downgrade or install a specific version of Composer, follow the instructions in this ITtutoria article.

How Can We Downgrade or Install a Specific Version of Composer?

Solution 1: Use Self-update

Self-update is a feature from Self Update Console that allows users to acquire information about the new update. The Self Update Console also provides a common workflow to analyze, download, and apply the updates. You can read more here.

The self-update command is the most efficient way to downgrade or update. For example, assuming you want to downgrade to version 1 of the Composer to fix some incompatible plugins, you should probably perform the following line in the terminal.

composer self-update --1

Then if you want to update Composer to version 2 after dealing with the tasks, run the below command.

composer self-update --2

This command will take the Composer to the latest version you want to install.

Solution 2: Apply the Rollback

First of all, we need to know what a Rollback is. Rollback is an operation to restore the database to a previous state. This action is canceling a transaction set or a particular transaction in order to return the database to a clean copy even after mistaken operations are performed. And to downgrade a Composer’s version by doing a Rollback, here are the steps to do it.

To start with, you need to run the command with -rollback after performing self-update

composer self-update --rollback

And your Composer will downgrade to its previous version.

To install the Composer to its newest version, run the following syntax

composer self-update

Solution 3: Install a Specific Version

If you want to program your project in a specific version of Composer, this solution is for you. To install a particular Composer version, you just need to add the exact version you want to use. For instance, if you are going to program on composer version 1.10.12, simply enter the following command in your terminal.

composer self-update 1.10.12

And you can check the current version by this command

composer self-update 1.10.12

And you can check the current version by this command

composer --version

Or this command for a shorter syntax

composer -V

Finally, here is a bonus for anyone that is feeling adventurous and wants to try the preview version. The command below allows you to install a pre-released version of Composer.

composer self-update --preview
