How to Resolve Composer Dependency Errors in Laravel Projects

Composer dependency error

If you encounter errors like missing files during Composer autoload, follow these steps:

Step 1: Backup the composer.lock file located in the Laravel project root.

Step 2: Delete the existing composer.lock file.

Step 3: Run composer install to regenerate the lock file and install dependencies.

Step 4: Restore the original composer.lock (if you need to revert to the previous dependency versions) and run composer install again.
