如何使用Composer获取PEAR.php？

Question

我安装了pear / archive_tar以与Phing一起使用，我使用Composer安装了Phing。但是，我收到了这个错误：

BUILD FAILED
exception 'BuildException' with message 'Error reading project file [wrapped: You must have installed the PEAR Archive_Tar class in order to use TarTask.]' in vendor/phing/phing/classes/phing/parser/ProjectConfigurator.php:197

我将PEAR repository添加到Composer并进行了更新，但仍然无效。

这个问题的后半部分分为here。

Answer 1

我将我的composer.json设置为此，并修复了它：

{
    "repositories": [
        {
            "type": "pear",
            "url": "http://pear.php.net"
        }
    ],
    "require": {
        "phing/phing" : "2.6.1",
        "pear-pear.php.net/pear": "*"
    }
}

像这样的Native Composer库不起作用，因为Composer不会将pear / archive_tar包添加到自动加载器中：

{
    "require": {
        "phing/phing" : "2.6.1",
        "rsky/pear-core-min" : "dev-master",
        "pear/archive_tar" : "1.3.11"
    }
}
