Root Cause

The PHP version installed on the system is incompatible with the version constraint specified in composer.json, preventing package installation or update.

中文

系统上安装的 PHP 版本与 composer.json 中指定的版本约束不兼容，阻止软件包安装或更新。

Workarounds

  1. 95% success Upgrade PHP to a version that satisfies the constraint (e.g., from 7.4 to 8.0): sudo apt update && sudo apt install php8.0 Or use a version manager like phpenv.

Or use a version manager like phpenv.
  2. 80% success If upgrading PHP is not possible, lower the php version constraint in composer.json to match the installed version (e.g., "php": ">=7.4") and run composer update --with-dependencies. Note: This may cause dependency conflicts.

中文步骤

  1. 将 PHP 升级到满足约束的版本（例如，从 7.4 升级到 8.0）：
sudo apt update && sudo apt install php8.0
或使用版本管理器如 phpenv。
  2. 如果无法升级 PHP，降低 composer.json 中的 php 版本约束以匹配已安装的版本（例如 "php": ">=7.4"），然后运行 composer update --with-dependencies。注意：可能导致依赖冲突。

Dead Ends

Common approaches that don't work:

  1. Editing composer.json to remove the php version constraint entirely 70% fail

    Composer may still require a minimum PHP version based on dependencies; removing the constraint can lead to runtime errors.

  2. Running composer install --ignore-platform-reqs to bypass the check 85% fail

    This installs packages that may not work on the current PHP version, causing fatal errors at runtime.
