我在使用時遇到了一些麻煩composer require dompdf/dompdf。我的結果是：Your requirements could not be resolved to an installable set of packages. Problem 1 - don't install symfony/var-dumper v4.0.12|don't install symfony/symfony v3.3.17 - don't install symfony/var-dumper v4.0.12|remove symfony/symfony v3.3.17 - don't install symfony/var-dumper v4.0.12|don't install symfony/symfony v3.3.17 - Installation request for symfony/var-dumper 4.0.12 -> satisfiable by symfony/var-dumper[v4.0.12]. - Installation request for symfony/symfony 3.3.17 -> satisfiable by symfony/symfony[v3.3.17].Installation failed, reverting ./composer.json to its original content.我已經刪除了我的供應商目錄，制作了一個composer update但我遇到了同樣的錯誤。

嘗試刪除
"symfony/var-dumper": "4.0.12"
并使用
"symfony/var-dumper": "3.3.*"
在您的 composer.json 中，因為 var-dumper v4.0.12 需要 symfony4 而您正在使用 symfony3
