Laravel is a free, open-source PHP web framework created by Taylor Otwell and intended to develop web applications which enable the model view controller architecture and are based on Symfony.

You are performing your duties and encountering the issue “Your lock file does not contain a compatible set of packages Please run composer update“. So, after some research, we’ll be here to explain possible solutions to programmers.

Why Does The Problem “Your Lock File Does Not Contain A Compatible Set Of Packages Please Run Composer Update” Happen?

You have been composing Laravel code for a long time. Besides, you are attempting to clone a task from GitHub and modify it locally. 

And you placed composer in your project directory, yet a vendor archive was missing. Then you attempted to run the composer setup process, but it returned the above problem.

In most situations, this is due to PHP 8. In our scenario, GitHub CI used PHP 8, although the project was written in PHP 7.4. The next part is all methods if you have numerous PHP installations (for example, 7.4 and 8 and the same server).

Your lock file does not contain a compatible set of packages. Please run composer update

How Will This Issue Be Resolved?

Solution 1: Run this code

If you are planning to run composer install, execute this instruction.

composer install --ignore-platform-reqs

When trying to launch a composer update, execute this prompt.

composer update --ignore-platform-reqs

Solution 2

In the composer.json file, clarify the PHP version.

"config": {

        "platform": {

            "php": "7.3"

        }

    },

If you already have the lock template committed, run the composer upgrade after attaching the above section to composer.json and submit the new lock archive afterward. Please remember that composer refresh will update the packages to the most recent versions.

Solution 3: Run the self-update –1

Run composer with the self-update –1 option. Here’s the action.

composer self-update --1

Solution 4: Follow these ways

1. Install php-intl using sudo pacman -S php-intl
2. Enable php intl by adjusting php config ( in my case /etc/php/php.ini ) . & extension=intl or uncomment the existing one
3. Restart apache or whatever you are using

Laravel is a open-source PHP framework built to support the development of software and applications, following the MVC architecture.
