Composer安装失败: react/http dev-master需要react/socket

Question

在运行"composer install“命令时，我遇到了以下问题：

$ composer install
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
- Installation request for react/http dev-master#cd15204bd15d106d7832c680e4fb0ca0ce2f5e30 -> satisfiable by react/http[dev-master].
- react/http dev-master requires react/socket ^1.0 || ^0.8.3 -> satisfiable by react/socket[v0.8.3, v0.8.4, v0.8.5, v0.8.6] but these conflict with your requirements or minimum-stability.
Problem 2
- react/http dev-master requires react/socket ^1.0 || ^0.8.3 -> satisfiable by react/socket[v0.8.3, v0.8.4, v0.8.5, v0.8.6] but these conflict with your requirements or minimum-stability.
- php-pm/php-pm dev-master requires react/http dev-master#cd15204bd15d106d7832c680e4fb0ca0ce2f5e30 -> satisfiable by react/http[dev-master].
- Installation request for php-pm/php-pm dev-master -> satisfiable by php-pm/php-pm[dev-master].

used composer.json

系统：

Distributor ID: Raspbian
Description:    Raspbian GNU/Linux 9.1 (stretch)
Release:        9.1
Codename:       stretch

在座有人知道如何解决这些问题吗？感谢您的帮助。

Answer 1

尝试通过以下方式调整composer.json

• minimum-stability to
• minimum-stability to prefer-stable to true (如果有稳定的包，仍然可以引入)

例如：

{
    "minimum-stability": "dev",
    "prefer-stable": true
}

然后运行：

$ composer require react/http:dev-master --update-with-dependencies
