- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
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:

我尝试这样解决问题:
这意味着我已经安装了 "symfony/validator": "^4.0"。但它没有任何建议?
最佳答案
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
将其添加到您的设置方法中:
$autoloader = require __DIR__ . '/your_folder_path/vendor/autoload.php';
AnnotationRegistry::registerLoader([$autoloader, 'loadClass']);
关于Symfony4 : The annotation does not exist, 或无法自动加载 |@Assert\NotBlank()|,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/49074243/
