Laravel 4: Fatal error: Class 'Patchwork\Utf8\Bootup' not found in autoload.php

Question

I added \"cviebrock/image-validator\": \"1.0.*\" to require section of composer.json. After, I ran composer update

Answer 1

This error seems to me like there is no patchwork/utf8 package installed.

See in your vendor folder whether the package exists or add in the require section in your composer.json file: "patchwork/utf8": "1.1.*" and then do composer update.
