我试图通过作曲家更新symfony。我解决了包中的大部分问题，但似乎无法解决此问题。这个错误对我来说毫无意义。
如果有人能帮忙，那就太好了！
Your requirements could not be resolved to an installable set of packages.
Problem 1
- The requested package sonata-project/notification-bundle (installed at 2.3.0, required as 3.1.0) is satisfiable by sonata-project/notification-bundle[2.3.0] but these conflict with your requirements or minimum-stability.
Problem 2
- Installation request for jms/security-extra-bundle 1.6.1 -> satisfiable by jms/security-extra-bundle[1.6.1].
- Can only install one of: jms/security-extra-bundle[1.6.1, 1.5.x-dev].
- Installation request for jms/security-extra-bundle (installed at 1.5.x-dev, required as 1.6.1) -> satisfiable by jms/security-extra-bundle[1.5.x-dev].

!!这不是更好的解决方案!!..而是一个解决方案。
我经常在运行作曲家安装之前和之后删除 composer.lock 文件。这通常可以解决我的问题。
我更新了另一个依赖项并运行了作曲家安装。现在一切都很好。
