Sylius安装崩溃，因为“未定义标识符”

我正在尝试在 ubuntu 上安装 Sylius 1.8，并且在运行时按照安装指南进行操作，但出现composer install以下错误：

Run composer recipes at any time to see the status of your Symfony recipes.

Script @auto-scripts was called via post-install-cmd

我也使用过 Sylius docker，但结果是一样的，似乎 Api-Platform 存在问题。

回答

composer create-project sylius/sylius-standard app_dir --no-install --no-scripts 
cd app_dir
composer require api-platform/core:2.5.9 --no-update 
composer install

{
    "conflict":  {
        "api-platform/core": ">=2.6.0"
    }
}
