laravel - Laravel 5 的 Composer 更新错误 - 未找到 'PHPExcel_Shared_Font'

Question

我需要自定义一个我在 packagist 上找到的包，所以我克隆了 github 上的 repo 并更新了我的 composer.json文件以从那里获取依赖项。

现在当我运行时 composer update我得到以下信息:

[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)
[113.1MB/17.54s] Writing lock file
[113.1MB/17.55s] Generating autoload files

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

我撤销了更改，并再次运行“composer update”并收到以下消息:

[4.4MB/0.33s] Loading composer repositories with package information
[4.7MB/1.48s] Updating dependencies (including require-dev)
[258.9MB/15.11s] Your requirements could not be resolved to an installable set of packages.

有谁知道我哪里出错了？

Answer 1

根据您自己的评论@TimothyBuktu，serverfireteam/blog需要 Laravel 5.1。

您需要锁定 serverfireteam/blog 的版本至 dev-master#c0039d3ade67503d674093f3a56d7b1540ae958d在您的 composer.json ，这是laravel的要求被撞到5.1之前的最后一次提交

或者，如果您仍想接收包的更新，则需要将应用程序更新到 Laravel 5.1。 http://laravel.com/docs/5.1/upgrade
