Php 编写器错误：无法将您的需求解析为可安装的包集

我在我们的项目中使用PHP7.4和laravel。我们两人一组正在进行这项工作。因此，每当我的同事添加软件包时，我都必须运行composer install来安装软件包。但现在，当我尝试运行composer安装时，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-xsl.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

如何解决此问题？

使用

--ignore platform reqs

选项，用于编写器命令，如

install

，

update

等，以忽略平台要求

--忽略平台要求：忽略php、hhvm、lib-*和ext-*要求，并强制安装，即使本地计算机未满足这些要求。另请参见平台配置选项

所以你可以试试看

composer install --ignore-platform-reqs

---

原始答案：

缺少所需的扩展名。通过以下方式安装：

---

sudo apt get install php7.4-zip

这可能很有用，但也有一个缺点：如果您运行的是旧版本的php并强制忽略它，您可能会看到一些错误，因为我知道的版本不正确，但他没有指定他使用的系统，以便我能给他完整的答案，例如，如果他使用的是

CentOS

，您的答案将不起作用。通常，这不是一个好主意。如果应用程序需要

ext-zip

，则应安装该应用程序。到目前为止，您尝试了什么？你被困在哪里？
