我尝试在 Laravel 5 中安装 Laravel-elfinder。在它的GitHub 页面 中，有一个我遵循的分步教程，但它不起作用。

我在装有 Windows 8 的 Windows PC 上安装了 XAMPP Web 服务器。

基本上我要去我的项目文件夹并执行

composer require barryvdh/laravel-elfinder

几秒钟后，我得到了这个错误：

C:\xampp\htdocs\edent>composer require barryvdh/laravel-elfinder
Using version 0.3.* for barryvdh/laravel-elfinder
./composer.json has been updated
Loading composer repositories with package information

Your requirements could not be resolved to an installable set of packages.

有谁知道我该如何解决这个问题？

您通过 composer 安装的所有公共包在packagist.org中都是“可搜索的” 。所以，如果你在 packagist 中搜索 laravel-elfinder，你会看到这个页面。

在那里，你会看到一个Requires列表，这意味着你看到的包依赖于另一个包，在安装这些依赖项之前你将无法使用你想要的包。但是，由于Composer非常聪明，它会尝试为您解决这些依赖关系。

在您的情况下，Composer 会尽可能多地解析。基本上，barryvdh/laravel-elfinder依赖于barryvdh/elfinder-flysystem-driver，而 barryvdh/elfinder-flysystem-driver 又依赖于 interactivity /image。如果你去后面的包，你会看到这样的 Requires 列表：

需要
php: >=5.3.0
ext-fileinfo: *

我已经写了所有这些，因此您可以理解为什么在您的消息转储中，您会看到多条消息说明

干预/图像 2.1.3需要 ext-fileinfo * -> 您的系统中缺少请求的 PHP 扩展文件信息。

基本上，这意味着您需要在 PHP 安装中启用扩展文件信息。

首先，打开您的php.ini并检查您是否没有评论扩展名。寻找这样的东西：

#[PHP_FILEINFO]
#extension=php_fileinfo.dll

如果找到它，请取消注释（删除#）并重新启动 XAMPP。

如果不这样做，您将需要与您的 PHP 安装相匹配的文件中的文件php_fileinfo.dll（可以在PHP For Windows下载页面中获取），.zip并且您会在文件夹中找到该ext文件。

将该文件复制到您的扩展文件夹中，编辑php.ini并添加它

[PHP_FILEINFO]
extension=php_fileinfo.dll

重新启动你的 XAMPP，你就完成了。

安装扩展后，composer再次运行该命令。
