我试图通过composer更新symfony。 我解决了我的包中的大多数问题，但似乎无法解决这个问题。 这个错误对我来说没有意义。
如果有人可以提供帮助，那就太棒了！
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].

我更新了另一个依赖项并运行了composer install。 一切都很好。

!!!这不是更好的解决方案！ ..但是解决方案。
我经常在运行composer install之前和之后删除composer.lock文件。这经常解决我的问题。
