当我尝试通过以下方式删除数据库架构时：

$ vendor/bin/doctrine orm:schema-tool:drop --force

我不断收到此错误：

In AnnotationException.php line 54:
[Semantical Error] The annotation 
"@Symfony\Component\Validator\Constraints  
\NotBlank" in property App\Entity\User::$plainPassword does not exist, 
or could not be auto-loaded.

这是我的 User.php：

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
use Doctrine\Common\Collections\ArrayCollection;

use Symfony\Component\Security\Core\User\AdvancedUserInterface;


/**

*/

class User implements UserInterface, \Serializable
{
/**
 * @var int
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;

/**

 */
private $username;

/**

private $plainPassword;


/** @ORM\Column(type="string", length=64)

private $password;

/**

 */
private $email;

/**
 * @ORM\Column(name="is_active", type="boolean")
 */
private $isActive;

/** @ORM\Column(type="datetime") * */
protected $created_at;

/** @ORM\Column(type="datetime", nullable=true) * */
protected $last_login;

/**

 * @ORM\OneToMany(targetEntity="Video", mappedBy="uploadedBy")
 */
protected $videos;

public function __construct()
{
    $this->isActive = true;
    $this->videos = new ArrayCollection();
}


public function getId()
{
    return $this->id;
}

public function getUsername(): ?string //php7.1
{

public function serialize()

    return serialize(array(

public function unserialize($serialized)
{
    list (
        $this->id,
        $this->username,
        $this->password,
        $this->isActive,
    ) = unserialize($serialized);
}

public function getCreatedAt()
{
    return $this->created_at;
}

public function getLastLogin()
{
    return $this->last_login;
}

public function setUsername(string $username) //php7
{
    $this->username = $username;
}

public function setEmail($email)
{
    $this->email = $email;
}

public function setPlainPassword($password)
{
    $this->plainPassword = $password;
}

public function setPassword($password)
{
    $this->password = $password;
}

public function setCreatedAt($created_at)
{
    $this->created_at = $created_at;
}

public function setLastLogin($last_login)
{
    $this->created_at = $last_login;
}

public function addVideo(Video $video)
{
    if (!$this->hasVideo($video)) {
        $this->videos->add($video);
    }
}

public function deleteVideo(Video $video)
{
    if ($this->hasVideo($video)) {
        $this->videos->removeElement($video);
    }
}

public function hasVideo(Video $video)
{
    return $this->videos->contains($video);
}

public function getVideos()
{
    return $this->videos;
}

public function isAccountNonExpired()
{
    return true;
}

public function isAccountNonLocked()
{
    return true;
}

public function isCredentialsNonExpired()
{
    return true;
}

public function isEnabled()
{
    return $this->isActive;
}
}

我试图以这种方式解决问题：

Symfony4：注解不存在，或无法自动加载（Symfony\Component\Validator\Constraints）

这意味着我已经安装了 "symfony/validator": "^4.0"。但它没有任何建议吗？

您这边的问题是因为您缺少一个注册需要加载的注释的包。

因此，您可以安装以下软件包：

symfony/phpunit-bridge

或者

在你的设置方法中添加这个：

$autoloader = require __DIR__ . '/your_folder_path/vendor/autoload.php';
AnnotationRegistry::registerLoader([$autoloader, 'loadClass']);

检查是否启用了FrameworkBundle 配置（“框架”） 验证注释。在文件中查看验证下config/packages/framework.yaml的选项enable_annotations是否正确设置为true（默认为 false）

例如：

framework:
    secret: '%env(APP_SECRET)%'
    validation:      { enable_annotations: true }

希望这有帮助
