symfony4.1.3 The import Doctrine\Bundle\FixturesBundle\Fixture cannot be resolved

Question

I am learning Symfony 4.1.3.

I have created my demo project with composer:

composer -V: Composer version 1.7.1 2018-08-07 09:39:23

I have installed orm-fixtures:

composer require orm-fixture
    Using version ^3.0 for doctrine/doctrine-fixtures-bundle
    ./composer.json has been updated
    Loading composer repositories with package information
    Updating dependencies (including require-dev)
    Restricting packages listed in "symfony/symfony" to "4.1.*"
    Nothing to install or update
    Generating autoload files
    ocramius/package-versions:  Generating version class...
    ocramius/package-versions: ...done generating version class

I have then created my fixture:

php bin/console make:fixtures

A file src/DataFixtures/ArticleFixtures.php has been created:

<?php
namespace App\DataFixtures;

use Doctrine\Common\Persistence\ObjectManager;
use Doctrine\Bundle\FixturesBundle\Fixture;

class ArticleFixtures extends Fixture
{

    public function load(ObjectManager $manager)
    {
        // $product = new Product();
        // $manager->persist($product);
        $manager->flush();
    }
}

And then the line use Doctrine\Bundle\FixturesBundle\Fixture;is underlined in red with the following message:

The import Doctrine\Bundle\FixturesBundle\Fixture cannot be resolved

I am stuck with this error, I do not know how to fix it. Any help would be appreciated.

Answer 1

I had the same problem while using Visual Studio Code and Symfony 5. Just close the IDE, open it again and the errors are gone.
