HI. I have the same problem.

Hi. Remove ../storage/framework/compiled.php

Yes, "php artisan clear-compiled" command does it but it is only temporary solution.

I played with this a bit and figured out the fix.

If you open the file "/vendor/laravel/framework/src/Illuminate/Foundation/Console/Optimize" and scroll down to line ~200 you'll see the following:

    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Expression/Expression.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Iterator/MultiplePcreFilterIterator.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Iterator/PathFilterIterator.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Iterator/ExcludeDirectoryFilterIterator.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Iterator/RecursiveDirectoryIterator.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Iterator/FilterIterator.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Iterator/FileTypeFilterIterator.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Shell/Shell.php',

Move the line ending in "FilterIterator.php" above "MultiplePcreFilterIterator.php" like so:

    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Expression/Expression.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Iterator/FilterIterator.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Iterator/MultiplePcreFilterIterator.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Iterator/PathFilterIterator.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Iterator/ExcludeDirectoryFilterIterator.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Iterator/RecursiveDirectoryIterator.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Iterator/FileTypeFilterIterator.php',
    $basePath.'/vendor/symfony/finder/Symfony/Component/Finder/Shell/Shell.php',

Now you should be able to run php artisan optimize and your app will work
