Symfony 4登录表单安全性FileLoaderLoadException

Question

I'm actually in a new Symfony 4 project and I got an Error 我实际上在一个新的Symfony 4项目中，但出现错误

FileLoaderLoadException FileLoaderLoadException

There is no extension able to load the configuration for "security" (in /home/connexio/dev/project/config/packages/security.yaml). 没有扩展能够加载“安全性”的配置（在/home/connexio/dev/project/config/packages/security.yaml中）。 Looked for namespace "security", found "framework", "doctrine_cache", "doctrine", "doctrine_migrations", "twig" in /home/connexio/dev/project/config/packages/security.yaml (which is loaded in resource "/home/connexio/dev/project/config/packages/security.yaml"). 在/home/connexio/dev/project/config/packages/security.yaml（已加载到资源中）中查找名称空间“ security”，找到“ framework”，“ doctrine_cache”，“ doctrine”，“ doctrine_migrations”，“ twig” “ /home/connexio/dev/project/config/packages/security.yaml”）。

I guess that I didn't understand the magic tricks of this tutorial. 我想我不了解本教程的魔术。 (The undefined routes leaves me puzzled) （不确定的路线让我感到困惑）

https://symfony.com/doc/current/security/form_login_setup.html https://symfony.com/doc/current/security/form_login_setup.html

I precise that I didn't configure my config/routes.yaml cause they didn't ask to and I didn't install FOSUserBundle cause it's not a symfony 4 bundle. 我精确地说，我没有配置config/routes.yaml因为他们没有要求，并且我没有安装FOSUserBundle因为它不是symfony 4捆绑包。 Instead of that my files are quite the same. 代替的是，我的文件完全相同。

Anyone have an advice to fix it ? 有人建议修复它吗？

Thanks for reading ! 谢谢阅读！

Answer 1

You are missing security component. 您缺少security组件。 Running composer req security should fix your problem. 运行composer req security应该可以解决您的问题。
