作曲家要求未能安裝包

Question

我有一個作曲家項目，需要在主項目composer.json文件中的供應商/包-1，供應商/包-1需要在包的composer.json中的供應商/包-2 -1。我目前安裝了vendor/package-1的版本1.18.11和vendor/package-2的版本2.3.2。我想更新到新的供應商/包版本1 1.19 *（需要版本2.4 *從供應商/包-2。）並執行：

composer require vendor/package-1:1.19.* 

失敗並輸出I得到的是

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[v2.4.1, 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. 

作曲家是否需要命令需要爲所有依賴項指定？如果我嘗試

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

它的作品，但它不應該有必要指定每個依賴項，對不對？

Answer 1

看起來像vendor/package2在固定版本中需要2.3.2或2.3。*，並且不能更新到2.4。

通常您應該嘗試放鬆版本要求以允許兼容的更新。使用波浪符操作符爲此，需要package2爲〜2.3（至少2.3，只要它不是不兼容的版本3，則更新）。這同樣適用於package1：如果你需要包含在1.19行中的功能，你需要〜1.19。
