php - Composer : conflict with your requirements or minimum-stability

Question

我正在尝试运行 composer require phpseclib/mcrypt_compat:dev-master在一个空目录中，并收到以下错误:

./composer.json has been created
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 phpseclib/mcrypt_compat dev-master -> satisfiable by phpseclib/mcrypt_compat[dev-master].
    - phpseclib/mcrypt_compat dev-master requires phpseclib/phpseclib dev-master -> satisfiable by phpseclib/phpseclib[d
ev-master] but these conflict with your requirements or minimum-stability.


Installation failed, deleting ./composer.json.

我不明白。 https://github.com/phpseclib/phpseclib/blob/master/composer.json说最低要求的 PHP 版本是 5.6.1。还有两个其他库是必需的，但 Composer 并不是说​​其他​​库不兼容 - Composer 说 phpseclib/phpseclib 不兼容。

这是我输入 php -v 时得到的输出:

PHP 7.0.26 (cli) (built: Nov 22 2017 13:19:37) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies

PHP 7.0.26 比 PHP 5.6.1 更新，PHP 5.6.1 是 phpseclib/phpseclib:dev-master 所需的最低版本。

有任何想法吗？

Answer 1

创建指定了最低稳定性的 composer.json 文件:

{
     "require": {
         "phpseclib/mcrypt_compat": "dev-master"
      },
     "minimum-stability": "dev"
}

http://getcomposer.org/doc/04-schema.md#minimum-stability

如果未指定，最低稳定性默认为稳定。
