Composer 错误：无法将您的要求解析为一组可安装的软件包

如何解决Composer 错误：无法将您的要求解析为一组可安装的软件包

我正在为我们的项目使用 PHP 7.4 和 laravel。我们正在以两人为一组进行工作。所以每当我的同事添加一个包时，我都必须运行 composer install 来安装这个包。但是现在当我尝试运行 composer install 时，出现以下错误：

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

  Problem 1
    - Installation request for spatie/laravel-backup 6.15.0 -> satisfiable by spatie/laravel-backup[6.15.0].
    - spatie/laravel-backup 6.15.0 requires ext-zip ^1.14.0 -> the requested PHP extension zip is missing from your system.

  To enable extensions,verify that they are enabled in your .ini files:
    - /etc/PHP/7.4/cli/PHP.ini
    - /etc/PHP/7.4/cli/conf.d/10-MysqLnd.ini
    - /etc/PHP/7.4/cli/conf.d/10-opcache.ini

    - /etc/PHP/7.4/cli/conf.d/20-xmlwriter.ini
    - /etc/PHP/7.4/cli/conf.d/20-xsl.ini
  You can also run `PHP --ini` inside terminal to see which files are used by PHP in CLI mode.

我应该如何解决这个问题？

解决方法

缺少所需的扩展名。通过以下方式安装：

sudo apt-get install php7.4-zip

,

对 --ignore-platform-reqs、install 等 Composer 命令使用 update 选项以忽略平台要求。

--ignore-platform-reqs：忽略 php、hhvm、lib-* 和 ext-* 要求并强制安装，即使本地机器不满足这些。另请参阅平台配置选项。

https://getcomposer.org/doc/03-cli.md

所以你可以试试

composer install --ignore-platform-reqs

原答案：Override PHP base dependency in composer
