Root composer.json需要php^7.3，但您的php版本（8.0.0）不满足该要求

运行

composer安装

命令时出现异常错误。它需要PHP7.3，而我有PHP8.0.0。这个静默与其他版本不同，因为我的PHP（8.0.0）版本比要求的要高，我只是想知道它为什么不工作

这是因为在composer.json文件中的项目中，您有：

"require": {
    "php": ">=7.3",
    .....
},

尝试将此要求更新为：

"require": {
    "php": "^7.3|^8.0",
    .....
},

我的问题与此不同，因为我的版本比要求的版本高。是的，但您也可以模拟回答中提到的平台。^7.3表示版本7.3.0或更高版本。但是，它与版本8或更高版本不兼容，具体取决于。你通过docker工作吗？这意味着您的容器具有所需的php版本。如果您在更新之外尝试，并且您的操作系统的php版本更高，那么您将得到此警告。解决此问题的一种方法是使用标志--ignore-platform-reqs运行编写器更新。应使用双管而不是单管。单一的方法仍然有效，但只适用于子孙后代：这不是解决这一问题的适当方法。它不起作用。你可以从这里看到代码和错误我不同意。。。您有：gabrielbull/ups api 0.8.0需要php^5.5 | | ^7.0->您的php版本（8.0.1）不满足该要求。因此，您必须使用php解释器版本5.5或7.0及以上。但是你有8.0.1。因此，首先，您必须将包gabrielbull/ups api更新到1.2.0版或更高版本，这对我不起作用！仍然获得相同的输出。
