Aqui está o erro que estou recebendo:

Script php artisan optimize handling the post-update-cmd event returned with an error

[RuntimeException]  
Error Output:

update [--prefer-source] [--prefer-dist] [--dry-run] [--dev] [--no-dev] [--lock] [--no-plugins] [--no-custom-installers] [--no-scripts] [--no-progress] [--with-dependencies] [-v|vv|vvv|--verbose] [-o|--optimize-autoloader] [packages1] ... [packagesN]

Isso mostra depois:

Writing lock file
Generating autoload files

Tentei excluir todas as minhas pastas na minha pasta de fornecedores. Mas isso não mudou nada.

Estou usando o servidor MAMP no meu Mac OS X.

Versão do PHP 5.4.10

mcrypt 2.5.8

Eu apenas tentei "sudo compositer update --verbose" e recebi este erro:

sudo composer update --verbose
Password:

Aqui está o erro que encontrei nos meus logs de erro do PHP:

[04-Nov-2013 20:45:44 Europe/Berlin] PHP Fatal error:  Class 'Patchwork\Utf8\Bootup' not found in /Applications/MAMP/htdocs/-----/bootstrap/autoload.php on line 46

Eu apenas tentei testar meu compositor:

sudo composer diagnose
Password:
Checking platform settings: OK
Checking http connectivity: OK
Checking composer.json: FAIL
No license specified, it is recommended to do so. For closed-source software you may use "proprietary" as license.
Name "andrew13/Laravel-4-Bootstrap-Starter-Site" does not match the best practice (e.g. lower-cased/with-dashes). We suggest using "andrew13/laravel-4-bootstrap-starter-site" instead. As such you will not be able to submit it to Packagist.
Checking disk free space: OK
Checking composer version: OK

Apenas apliquei a recomendação na mensagem de erro do último comando. Agora tudo está mostrando como OK.

Eu apenas tentei isso:

curl -sS https://getcomposer.org/installer | php -- --check
#!,/usr/bin/env php
All settings correct for using Composer

Agora estou recebendo novos erros nos meus logs de erros do PHP:
