php - Composer require 安装包失败

Question

我有一个 composer 项目需要主项目 composer.json 文件中的 vendor/package-1，vendor/package-1 需要 package-1 的 composer.json 中的 vendor/package-2。我目前安装了 vendor/package-1 的 1.18.11 版和 vendor/package-2 的 2.3.2 版。我想更新到新的 vendor/package-1 版本 1.19.*(需要来自 vendor/package-2 的版本 2.4.*)并执行:

composer require vendor/package-1:1.19.*

失败，我得到的输出是

Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - vendor/package-1 v1.19.2 requires vendor/package2 2.4.* -> satisfiable by vendor/package2[v2.4.3, v2.4.0, v2.4.1, v2.4.2].
    - vendor/package-1 v1.19.1 requires vendor/package2 2.4.* -> satisfiable by vendor/package2[v2.4.3, v2.4.0, v2.4.1, v2.4.2].
    - vendor/package-1 v1.19.2 requires vendor/package2 2.4.* -> satisfiable by vendor/package2[v2.4.3, v2.4.0, v2.4.1, v2.4.2].
    - Can only install one of: vendor/package2[v2.3.2, v2.4.3].
    - Can only install one of: vendor/package2[v2.4.0, v2.3.2].
    - Can only install one of: vendor/package2[v2.4.1, v2.3.2].
    - Can only install one of: vendor/package2[v2.4.2, v2.3.2].
    - Can only install one of: vendor/package2[v2.4.3, v2.3.2].
    - Installation request for vendor/package2 == 2.3.2.0 -> satisfiable by vendor/package2[v2.3.2].
    - Installation request for vendor/package-1 1.19.* -> satisfiable by vendor/package-1[v1.19.1, v1.19.2].

Installation failed, reverting ./composer.json to its original content.

是否需要为所有依赖项指定 composer require 命令？如果我尝试

composer require vendor/package-1:1.19.* vendor/package-2:2.4.*

它可以工作，但不需要指定每个依赖项，对吧？

Answer 1

似乎 vendor/package2 在固定版本 2.3.2 或 2.3.* 中是必需的，无法更新到 2.4。

通常您应该尝试放宽版本要求以允许兼容更新。为此使用波浪号运算符，要求 package2 为 ~2.3(最低 2.3，只要它不是不兼容的版本 3 就更新)。这同样适用于 package1:如果您需要 1.19 行中包含的功能，则需要 ~1.19。
