有人能帮我吗？我也试图解决这个问题

php artisan缓存：清除

php-artisan-config:cache

删除项目目录中的

composer.lock

文件，然后运行以下命令：

composer install

composer require barryvdh/laravel-dompdf:0.8.2

或者您可以尝试运行以下命令：

composer install

composer require barryvdh/laravel-dompdf:0.8.2

类似的问题已在

Composer github存储库中列出

出现此问题的原因是代理配置不正确。请检查代理配置

此外，如果您正在使用任何防病毒软件，请将其禁用，然后重试
