我需要在我的项目中安装DomPDf。所以，我添加“barryvdh/laravel-dompdf”：“v0.7.0”，作曲家需要阻止。当我更新错误以后的作曲家显示。请告诉我我的错误....请指定要我..您的要求无法解决：无法打开流：权限被拒绝
终端错误

我也试过：
composer require barryvdh/laravel-dompdf
但它显示以下错误：

同样的错误发现... @Plxx问题1 - DOMPDF/DOMPDF v0.8.0需要phenx/PHP -font-lib 0.5。* - >找不到匹配的包。 - barryvdh/laravel-dompdf v0.8.0要求dompdf/dompdf^0.8 - >可通过dompdf/dompdf [v0.8.0]满足。 - barryvdh/laravel-dompdf v0.8.0的安装请求 - >可由barryvdh/laravel-dompdf [v0.8.0]满足。 – Karthikvijayaveni
我刚刚测试了一个全新的laravel安装过程，它工作得很好。你在使用最新的作曲家版本（1.3.2）吗？ – Plxx
Composer版本是1.3.0。如何升级作曲家版本。@Plxx – Karthikvijayaveni
