laravel artisan error when listing routes - php

Question

I'm a bit new to laravel and have come across something I don't know how to fix, or even where to start looking. Can anyone explain this, please?
When I run php artisan route:list
I get:
[Symfony\Component\Debug\Exception\FatalErrorException]
syntax error, unexpected ','
I've only made a couple of changes to routes.php. Have since commented those out and cleared the cache, but this still shows, regardless.
Update - Contents of routes.php
<?php
/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.

]);
Even checking my routes.php - shows no errors:
php -l app\http\routes.php
No syntax errors detected in app\http\routes.php

Answer 1

Try to go to storage/framework and delete routes.php. I suspect that the syntax error might have been cached.

Answer 2

I had this error, but only when ran on my local computer. If I ran route:list on server, it worked fine. The problem was my computer was using PHP v5.6 and the server was using PHP v7.0.
I was using the new ?? operator in a controller, so it was throwing a syntax error cause PHP v5.6 doesn't understand that operator.
