使用composer安装PEAR扩展HTTP_Request2

Question

我有一个composer.json文件:

{
    "name": "vendor/Project",
    "description": "description_text",
    "repositories": [
        {
            "type": "pear",
            "url": "http://pear.php.net"
        }
    ],
    "require": {
        "jakeasmith/http_build_url": "dev-master",
        "phpmailer/phpmailer": "dev-master",
        "pear-pear/Text_Diff": "*",
        "pear-pear/Net_IDNA2": "*",
        "pear-pear/HTTP_Request2": "2.2.1"
    },
    "require-dev": {
        "phpunit/phpunit": "< 4.0.0"
    }
}

当我尝试执行命令时,php composer.phar install我得到了这个:

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

  Problem 1
    - Installation request for pear-pear/http_request2 2.2.1 -> satisfiable by pear-pear.php.net/HTTP_Request2[2.2.1].
    - pear-pear.php.net/HTTP_Request2 2.2.1 required pear-pear.php.net/net_url2 >=2.0.0.0 -> no matching package found.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting

为什么我收到错误？我应该在我的composer.json文件中真正存储所有pear依赖项HTTP_Request2吗？

PS如果我运行php composer.phar install与

"pear-pear/Archive_Tar": "*",
"pear-pear/Console_Getopt": "*",
"pear-pear/Structures_Graph": "*",
"pear-pear/XML_Util": "*",
"pear-pear/PEAR": "*",
"pear-pear/Net_URL2": "*"

然后添加一个字符串:"pear-pear/HTTP_Request2": "2.2.1"并运行php composer.phar update- 一切都像魔术一样工作!但我认为这不是正确的方法.

Answer 1

通过重命名修复:

"pear-pear/HTTP_Request2": "2.2.1"

至

"pear-pear.php.net/HTTP_Request2": "2.2.1"
