Symfony 2.8>；3.4.22-无法将您的要求解析为一组可安装的软件包

我正在搜索有关堆栈溢出的此错误，但没有找到任何相关信息

最近我将Symfony 2.8更新为3.4.22，现在我必须使用composer更新一些捆绑包，21个捆绑包中有3个在升级时出现问题

这些捆绑包是： -symfony/信条桥 -friendsofsymfony/用户包 -friendsofsymfony/oauth服务器包

当我尝试手动安装这些捆绑包时，composer的输出是：

Using version ^4.2 for symfony/doctrine-bridge
./composer.json has been updated

如何解决这些依赖关系

欢迎任何帮助

• 编辑1：我正在尝试重新安装捆绑包，而不是更新 旧包
• 编辑2:PHP版本=>7.1.26
以下是解决方案：
在composer.json中，更改：

"paragonie/random_compat": "^2.1",

通过此选项（如果您没有，请添加）：
并在同一文档中删除此行：

"symfony/doctrine-bridge" : "~2.1",

然后，做一个作曲家更新，对我来说，它就像一个魅力

谢谢大家
问题如此之多的原因在于没有一颗灵丹妙药。这要看情况而定。就我个人而言，我会创建一个新的project 3.4项目，然后需要每个附加的第三方包。希望他们都有一个支持3.4的版本。这至少给了我一个起点。理论上，您可以用新的composer.json文件替换现有的composer.json文件，删除供应商目录，安装并交叉手指。@Cerad这正是我正在做的事情@Fabian I当前更新到Symfony 3.4的可能副本，问题是不同的，因为我正在尝试新的捆绑包安装PHP版本？确保您的php控制台版本至少为5.6。假设您从“composer create project symfony/framework standard edition”开始，则会自动安装条令桥，因此无需更新它。我刚刚创建了一个新的3.4版本，并毫无问题地安装了fos捆绑包。我碰巧正在使用PHP7.3。

"symfony/doctrine-bridge" : "~2.1",
