Target class [composer] does not exist in the current project. How to solve this issue?

When you encounter the error message "Target class [composer] does not exist in the current project," it usually means that Composer, the dependency manager for PHP, is not installed or not properly configured in your project. Here are some steps you can take to resolve this issue:

Check if Composer is installed:
- Open your terminal or command prompt and type composer --version. If Composer is installed, you should see the version number displayed. If not, you need to install it first.
Install Composer:
- Go to the Composer download page (https://getcomposer.org/download/) and download the installer for your operating system.
- Follow the instructions provided on the download page to install Composer.
Configure Composer:
- Create a composer.json file in the root directory of your project. This file will contain the dependencies for your project.
- Initialize Composer by running composer init in your terminal or command prompt. This will prompt you to enter some information about your project, such as its name, description, and author.
- Add dependencies to your composer.json file by editing it manually or using the composer require command. For example, to add a dependency on the Laravel framework, you would run composer require laravel/laravel.
Install dependencies:
- Once you have added dependencies to your composer.json file, run composer install in your terminal or command prompt to install them.
Check if the error persists:
- After installing Composer and dependencies, try running the command that caused the error again to see if it has been resolved.

If you have followed these steps and the error still persists, there may be other issues at play, such as incorrect file permissions or a misconfigured environment. In that case, you may need to consult the Composer documentation or seek help from the PHP community.
