php - 无法通过Composer安装phpDocumentor

在composer.json中，我有

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

这就是那里的内容，因为我正尝试使用./composer.phar install命令将phpDocumentor安装到一个隔离的文件夹中。但是我得到的是

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
    - phpdocumentor/phpdocumentor v2.0.0 requires phpdocumentor/template-abstract ~1.2 -> satisfiable by phpdocumentor/template-abstract[1.2, 1.2.1].

    - phpdocumentor/phpdocumentor v2.4.0 requires phpdocumentor/template-abstract ~1.2 -> satisfiable by phpdocumentor/template-abstract[1.2, 1.2.1].
    - phpdocumentor/phpdocumentor v2.3.1 requires dompdf/dompdf dev-master@dev -> no matching package found.
    - phpdocumentor/phpdocumentor v2.3.0 requires dompdf/dompdf dev-master@dev -> no matching package found.
    - phpdocumentor/template-abstract 1.2.1 requires ext-xsl * -> the requested PHP extension xsl is missing from your system.
    - phpdocumentor/template-abstract 1.2 requires ext-xsl * -> the requested PHP extension xsl is missing from your system.
    - Installation request for phpdocumentor/phpdocumentor * -> satisfiable by phpdocumentor/phpdocumentor[v2.0.0, v2.0.1, v2.1.0, v2.2.0, v2.3.0, v2.3.1, v2.3.2, v2.4.0].

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

最佳答案

错误消息表明您在PHP设置中缺少XSL扩展名。您可以看到http://www.php.net/manual/en/xsl.installation.php以获取有关安装该扩展程序的更多信息。

请注意，默认模板不需要XSL扩展名。您还可以选择使用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扩展名，因此可以安全地使用。
