如何解决Laravel问题？？您的需求无法被解决为一组可安装的软件包。

Question

我正在使用Windows操作系统运行PHPLaravel-8应用程序.我的中所有项目的PHP版本都是PHP-Version3.8。在我的本地系统中，所有Laravel项目都有("php"：“^7.3 x^8.0”，)

然而，我做了一个团队项目的拉请求，但它是4。该项目还使用了Laravel-8框架("php"：“^7.4 x^8.0”，)

当我试图在下载的项目上运行composer安装时，我得到了以下错误：

Your lock file does not contain a compatible set of packages. Please run composer update.

Problem 1
  - Root composer.json requires php ^7.4|^8.0 but your PHP version (7.3.8) does not satisfy that requirement.
  Problem 2
  - lcobucci/clock is locked to version 2.0.0 and an update of this package was not requested.
  - lcobucci/clock 2.0.0 requires php ^7.4 || ^8.0 -> your php version (7.3.8) does not satisfy that requirement.
Problem 3
  - lcobucci/jwt is locked to version 4.0.3 and an update of this package was not requested.
  - lcobucci/jwt 4.0.3 requires php ^7.4 || ^8.0 -> your php version (7.3.8) does not satisfy that requirement.
Problem 4
  - lcobucci/jwt 4.0.3 requires php ^7.4 || ^8.0 -> your php version (7.3.8) does not satisfy that requirement.
  - league/oauth2-server 8.2.4 requires lcobucci/jwt ^3.4 || ^4.0 -> satisfiable by lcobucci/jwt[4.0.3].
  - league/oauth2-server is locked to version 8.2.4 and an update of this package was not requested.

然后，当我更新composer时，错误就是：

Your requirements could not be resolved to an installable set of packages.

Problem 1
 - Root composer.json requires php ^7.4|^8.0 but your php version (7.3.8) does not satisfy that requirement.

所有的项目都使用composer-2。

如果我将我的本地系统升级到PHPV-7.4，我将对已部署的项目产生问题。

我怎么才能解决这个问题？

谢谢

Answer 1

打开composer.json文件并将版本替换为：

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

您还可以使用以下命令：

composer install --ignore-platform-reqs

编辑：

如果这样做不起作用或导致更多问题，我建议您更新PHP版本，然后您必须为旧项目指定PHP版本，并将它们绑定到使用PHP 7.3以避免任何问题。在更新composer.json之后，在每个旧项目的文件中添加以下行：

"config": {

  "platform": {

    "php": "7.3"

  }

},
