symfony - 将 SF 从 2.8 升级到 3.xx

Question

我在从 Symfony 2.8 迁移到 Symfony 3 及更高版本时遇到问题。几天来，我一直在尝试更新我的项目，但我阻止了同样的错误。我尝试了所有可以在谷歌上找到的解决方案，但没有改进。这是我的文件 composer.json

}

我使用此命令进行更新：$ composer update symfony/symfony --with-dependencies --no-scripts

更新未完成，因为显然我与我的依赖项的不同版本有冲突..但是我无法在更新的版本中更新我的依赖项

需要你的帮助请..

你有冲突，因为你不能同时拥有symfony/symfony 3.0.*和symfony/cache 3.4。

事实上，您锁定在某个版本的其他捆绑软件与 symfony 3.0 不兼容，因此您也需要升级它们。

最可行的方法是使用这些依赖项：

"symfony/symfony": "3.2.*",
"friendsofsymfony/user-bundle": "^2.0",
"sonata-project/user-bundle": "^4.0",

然后只需运行composer install而不是composer update symfony/symfony. Composer 将完成它的工作，然后您必须调整您的代码以减轻所有 BC 中断等...

如果您无法更改其他依赖项，那么您将被 Sf 2.8 困住。
