I am trying to run my test file, ImportCSVTest.php with the command ./vendor/bin/phpunit --filter=testNoImportFile

but I get the error of

/usr/bin/php declares an invalid value for PHP_VERSION.
This breaks fundamental functionality such as version_compare().
Please use a different PHP interpreter.

My test file, ImportCSVTest.php is as follows

<?php

namespace Tests\Feature;

use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Http\UploadedFile;
use Tests\TestCase;

class ImportCSVTest extends TestCase
{
    /**
     * A basic test example.
     *
     * @return void
     */
    public function testNoImportFile()
    {
        Storage::fake('products');

        $response = $this->json('POST', '/import', [
            'csv' => UploadedFile::fake()->create('emptyUpload', 0, null)
        ]);

        Storage::disk('products')->assertMissing('emptyUpload');
    }


}

First time I am coming across an error like this, how does one fix this?
