我正在Stack Overflow上搜索这个错误，但我找不到任何关于它的信息。
最近我更新了Symfony 2.8到3.4.22，现在我必须使用composer更新一些捆绑包，当我尝试升级它们时，21个捆绑包中的3个有问题。
这些包是： - symfony / doctrine-bridge - friendsofsymfony / user-bundle - friendsofsymfony / oauth-server-bundle
当我尝试手动安装这些包时，composer的输出是：
Using version ^4.2 for symfony/doctrine-bridge
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

我如何解决这些依赖关系？
欢迎任何帮助
这是解决方案：
在composer.json中，更改：
"paragonie/random_compat": "^2.1",
通过这个（如果你没有它，添加它）：
"paragonie/random_compat": ">=1",
并在同一文档中删除此行：
"symfony/doctrine-bridge" : "~2.1",
然后，让作曲家更新，对我来说，它就像一个魅力！
