Composer error:Your requirements could not be resolved to an installable set of packages

Question

我正在为我们的项目使用 php 7.4 和 laravel。我们正在以两人一组的形式开展工作。因此，每当我的同事添加一个包时，我都必须运行 composer install 来安装该包。但是现在当我尝试运行作曲家安装时，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/10-pdo.ini
    - /etc/php/7.4/cli/conf.d/15-xml.ini
    - /etc/php/7.4/cli/conf.d/20-bcmath.ini

    - /etc/php/7.4/cli/conf.d/20-dom.ini
    - /etc/php/7.4/cli/conf.d/20-exif.ini

    - /etc/php/7.4/cli/conf.d/20-sysvsem.ini
    - /etc/php/7.4/cli/conf.d/20-sysvshm.ini
    - /etc/php/7.4/cli/conf.d/20-tokenizer.ini
    - /etc/php/7.4/cli/conf.d/20-xmlreader.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.

我该如何解决？

Answer 1

对 install、update 等作曲家命令使用 --ignore-platform-reqs 选项以忽略平台要求。

--ignore-platform-reqs: ignore php, hhvm, lib-* and ext-* requirements and force the installation even if the local machine does not fulfill these. See also the platform config option.

所以你可以试试

composer install --ignore-platform-reqs

缺少所需的扩展。通过以下方式安装：

sudo apt-get install php7.4-zip
