Symfony 4.4：無法自動連接服務“Symfony\Component\Validator\Context\ExecutionContextFactory”

Question

我正在從 symfony 的框架版本 3 升級到 4.4。 我的基地正在運行。 但是我的自動化測試失敗了，因為框架本身缺少對某個需要翻譯器接口的文件的類型提示。

Symfony\Component\DependencyInjection\Exception\RuntimeException: Cannot autowire service "Symfony\Component\Validator\Context\ExecutionContextFactory": argument "$translator" of method "__construct()" has no type-hint, you should configure its value explicitly.

/srv/vendor/symfony/dependency-injection/Compiler/DefinitionErrorExceptionPass.php:54
/srv/vendor/symfony/dependency-injection/Compiler/AbstractRecursivePass.php:83
/srv/vendor/symfony/dependency-injection/Compiler/DefinitionErrorExceptionPass.php:32
/srv/vendor/symfony/dependency-injection/Compiler/AbstractRecursivePass.php:47
/srv/vendor/symfony/dependency-injection/Compiler/Compiler.php:94
/srv/vendor/symfony/dependency-injection/ContainerBuilder.php:762
/srv/vendor/symfony/http-kernel/Kernel.php:594
/srv/vendor/symfony/http-kernel/Kernel.php:136
/srv/vendor/symfony/framework-bundle/Test/KernelTestCase.php:79
/srv/tests/BaseTestCase.php:32 

導致此錯誤的文件。

    /**
     * Creates a new context factory.
     *
     * @param TranslatorInterface $translator        The translator
     * @param string|null         $translationDomain The translation domain to
     *                                               use for translating
     *                                               violation messages
     */
    public function __construct($translator, string $translationDomain = null)
    {
        if (!$translator instanceof LegacyTranslatorInterface && !$translator instanceof TranslatorInterface) {
            throw new \TypeError(sprintf('Argument 1 passed to "%s()" must be an instance of "%s", "%s" given.', __METHOD__, TranslatorInterface::class, \is_object($translator) ? \get_class($translator) : \gettype($translator)));
        }

        $this->translator = $translator;
        $this->translationDomain = $translationDomain;
    }

我似乎無法弄清楚是什么導致它無法加載或我應該如何修復它。 我已經嘗試將作曲家和大多數版本更新到 symfony 4.4 支持的最新版本。

這不是我的項目中需要這種類型提示的文件。 它是一個框架文件。

自動裝配無法猜測 $translator 的類型。 您必須指定 $translator 的類型：

    /**
     * Creates a new context factory.
     *
     * @param TranslatorInterface $translator        The translator
     * @param string|null         $translationDomain The translation domain to
     *                                               use for translating
     *                                               violation messages
     */
    public function __construct(TranslatorInterface $translator, string $translationDomain = null)
    {
        if (!$translator instanceof LegacyTranslatorInterface && !$translator instanceof TranslatorInterface) {
            throw new \TypeError(sprintf('Argument 1 passed to "%s()" must be an instance of "%s", "%s" given.', __METHOD__, TranslatorInterface::class, \is_object($translator) ? \get_class($translator) : \gettype($translator)));
        }

        $this->translator = $translator;
        $this->translationDomain = $translationDomain;
    }

use Symfony\Contracts\Translation\TranslatorInterface;
