当我在symfony 3.4.30安装上进行作曲家更新时，它会毫无问题地完成，但是当我尝试在创建的锁定文件上运行作曲家安装时，会引发错误。
这同时在我的CentOS服务器和MacOS笔记本电脑上发生。我安装了最新的作曲家：
有人知道发生了什么事吗？
我尝试完全删除供应商目录和composer.lock文件，但均未成功。我还更新了作曲家的版本，并清除了作曲家的缓存：

答案 0 :(得分：1)
您要解决的方法是删除行
"symfony/templating": "^4.1",
从您的composer.json，然后重试整个过程。
请记住，它将把您的symfony/templating版本降级为3.4.x，并可能导致副作用。
为什么？嗯，您的问题实际上出在这里：symfony / symfony的composer.json行：https://github.com/symfony/symfony/blob/3.4/composer.json#L77
并由https://getcomposer.org/doc/04-schema.md#replace
解释因此，实际上，当您安装symfony/symfony时，它可以代替同一版本的symfony/templating（在您的情况下为3.4.30），但是，您还可以在composer.json中获得说明，以将其安装为版本^4.3
这些行也告诉你：
- don't install symfony/symfony v3.4.30|remove symfony/templating v4.3.3
- don't install symfony/templating v4.3.3|don't install symfony/symfony v3.4.30
它实际上指示您安装symfony/symfony v3.4.30或symfony/templating v4.3.3，但不能同时安装，因为replace软件包的symfony/symfony指令使其完全相同打包为symfony/templating，但与您的情况不同。
实际上，作曲家文档也准确地告诉您：
这对于包含子软件包的软件包也很有用，例如 例如，主要的symfony / symfony软件包包含所有Symfony 也可以单独包装的组件。如果你 需要主程序包，它将自动满足任何要求 单个组件之一，因为它替代了它们。
