我想安装 Sonata Dashboard 包，所以我按照these 的步骤操作。

安装和配置后出现错误：

编译错误：Application\Sonata\DashboardBundle\Entity\Dashboard::getId() 的声明必须与 Sonata\DashboardBundle\Model\Dashboard::getId() 兼容：?int

我使用 Symfony 3.4、php 7.2 和 composer.json 看起来像：

"require": {
    "php": ">=5.5.9",
    "doctrine/doctrine-bundle": "^1.6",
    "doctrine/orm": "^2.5",

    "sonata-project/easy-extends-bundle": "^2.5",
    "sonata-project/formatter-bundle": "^3.4",
    "sonata-project/google-authenticator": "^2.1",
    "sonata-project/media-bundle": "^3.12",
    "sonata-project/news-bundle": "3.4",
    "sonata-project/notification-bundle": "^3.5",
    "sonata-project/seo-bundle": "^2.5",
    "sonata-project/user-bundle": "^4.1",

    "symfony/polyfill-apcu": "^1.0",

    "symfony/symfony": "3.4.*",
    "symfony/templating": "3.4.8",
    "twig/twig": "^1.0||^2.0"
},

有什么想法可能是错的吗？

【解决方案1】：

看起来生成的实体错过了返回类型提示……可能是a bug in Sonata Easy Extends bundle。您可以通过查找和修改Application\Sonata\DashboardBundle\Entity\Dashboard来添加类型提示

【讨论】：

现在我将 Dashboard.php 中的函数修改为：public function getId(): ?int {return $this->id;}。现在一切正常，除了当我转到 URL：admin/sonata/dashboard/dashboard/create 时，它会引发另一个错误：类型错误：返回值 Sonata\DashboardBundle\Model\Dashboard::getEnabled() 必须是boolean 类型，返回 null
听起来像另一个错误，这里应该有一个默认值：github.com/sonata-project/SonataDashboardBundle/blob/master/src/… 您可以覆盖设置器以将其设置为您认为应该是默认值的任何值，true 或 false。
