导读：在composer.json我有 { "require": { "phpdocumentor/phpdocumentor": "*" }} 它是什么,因为我正在尝试使用./composer.phar安装命令将phpDocumentor安装到一个隔离的文件夹中.但我得到的是 Loading composer repositories with package informationUpdating

在composer.json我有

{
    "require":
    {
        "phpdocumentor/phpdocumentor": "*"
    }
}

它是什么,因为我正在尝试使用./composer.phar安装命令将phpDocumentor安装到一个隔离的文件夹中.但我得到的是

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

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

该错误消息表明您在PHP安装程序中缺少XSL扩展.有关安装该扩展的更多信息,请参阅 http://www.php.net/manual/en/xsl.installation.php.

请注意,默认模板不需要XSL扩展名;您也可以选择使用PHAR可执行文件或可下载的存档.这些可以从https://github.com/phpDocumentor/phpDocumentor2/releases/latest下载.这两个不检查XSL扩展,因此可以安全使用.
