Laravel 5.4 when migrating getting too long error

I can fix this by going in the migration for the user's table, and manually specifying the max-length of the email field, like so:

$table->string('email', 250)->unique();

As outlined in the Migrations guide to fix this all you have to do is edit your AppServiceProvider.php file and inside the boot method set a default string length:

use Illuminate\Support\Facades\Schema;
public function boot()
{
    Schema::defaultStringLength(191);
}
