无法在 Symfony 上安装 sonata admin

Question

我完整安装了 symfony 4.4，然后尝试安装 sonata-project/doctrine-orm-admin-bundle。开箱即用，这是行不通的。有人可以解释一下吗？

我在使用 symfony 5 时遇到了同样的错误。

Your requirements could not be resolved to an installable set of packages.

Answer 1

使用 composer require "sonata-project/admin-bundle:^3.56" "twig/twig:^2.10"

Answer 2

在安装奏鸣曲之前，您需要安装指定版本的 twig 之一。

奏鸣曲依赖于 twig。
