【问题描述】：

我正在转换一个旧项目（具有旧依赖项）以使用 composer 管理它的依赖项。该站点使用 PEAR 的 Text_Password。我读到可以使用 composer 安装依赖项，在 composer.json 中添加（类似）以下内容：

"repositories": [
    {
        "type": "pear",
        "url": "http://pear.php.net"
    }
],
"require": {
    ...
    "pear-pear/Text_Password": "*"
},

..但我得到了错误：

$ composer update
Loading composer repositories with package information
Initializing PEAR repository http://pear.php.net
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - The requested package pear-pear/text_password could not be found in any version, there may be a typo in the package name.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion> for more details.

是否可以使用 Composer 安装 PEAR 库？我注意到在 packagist 上有一组 PEAR 库，但我看不到 Text_Password - https://packagist.org/packages/pear/

Text_Password 也有一个 github 存储库，但我认为直接从 PEAR 安装可能会更好？ - https://github.com/pear/Text_Password

无论如何，我怎样才能用 composer 安装这个包？

【解决方案1】：

给你：

{
    "type": "project",
    "repositories": [
        {
            "type": "pear",
            "url": "http://pear.php.net"
        }
    ],
    "require": {
        "pear-pear.php.net/Text_Password": "*"
    }
}

注意：PEAR 存储库已从 Composer 2.0 中删除
