Ошибка обновления Composer с Laravel 5 - 'PHPExcel_Shared_Font' не найден

Question

Мне нужно было настроить пакет, который я нашел на packagist, поэтому я клонировал репо на github и обновил файл composer.json, чтобы вместо этого получить зависимость от него.

Теперь, когда я бегу composer update я получаю следующее:

[4.5MB/0.34s] Loading composer repositories with package information 
[4.8MB/1.57s] Updating dependencies (including require-dev) 
[248.7MB/16.88s] - Removing serverfireteam/blog (master)

Fatal error: Class 'PHPExcel_Shared_Font' not found in C:\Users\Tim\Code\Laravel\config\excel.php on line 174 
PHP Fatal error: Class 'PHPExcel_Shared_Font' not found in C:\Users\Tim\Code\Laravel\config\excel.php on line 174 
[113.4MB/18.22s] Script php artisan clear-compiled handling the post-update-cmd event returned with an error 



    [RuntimeException] 
    Error Output: PHP Fatal error: Class 'PHPExcel_Shared_Font' not found in C:\Users\Tim\Code\Laravel\config\excel.php on line 174 

Я reveresed изменения, и побежал `обновление композитора снова и получить следующее сообщение:

[4.4MB/0.33s] Loading composer repositories with package information 
[4.7MB/1.48s] Updating dependencies (including require-dev)

Кто-нибудь знает, где Я ошибся?

Answer 1

Согласно вашему собственному комментарию @TimothyBuktu, serverfireteam/blog требует laravel 5.1.

Вы хотите заблокировать версию serverfireteam/blog на dev-master#c0039d3ade67503d674093f3a56d7b1540ae958d в вашем composer.json, которая является последней фиксации перед требованием Laravel была доведена до 5,1

В качестве альтернативы, если вы все еще хотите получать обновления для пакета, вам необходимо обновить приложение до laravel 5.1. http://laravel.com/docs/5.1/upgrade
