Question

我尝试在Laravel 5中安装Laravel-elfinder。在它的GitHub page 我已经按照一步一步的教程进行了操作，但它无法正常工作。

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

几秒钟后我收到了这个错误：

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

有没有人知道如何解决这个问题？

您通过编辑器安装的所有公共包都是packagist.org中的“可搜索”。所以，如果你在packagist中搜索laravel-elfinder，你最终会at this page。

在那里，您会看到需要的列表，这意味着您看到的包依赖于另一个包，在安装之前您将无法使用所需的包那些依赖。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会尽可能地解析。基本上， barryvdh/laravel-elfinder 取决于 barryvdh/elfinder-flysystem-driver ，而 intervention/image 依赖于 PHP For Windows 。如果你转到后面的软件包，你会看到Requires列表：

<强>要求
  php：＆gt; = 5.3.0
  ext-fileinfo：*

我写了这一切，所以你可以理解为什么，在你的消息转储中，你看到多条消息说明

干预/图像2.1.3 需要ext-fileinfo * - ＆gt;系统中缺少所请求的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 fileinfo 。

首先，打开php.ini并检查您是否没有评论扩展程序。寻找这样的东西：

#[PHP_FILEINFO]
#extension=php_fileinfo.dll

如果找到，请取消注释（删除#）并重新启动XAMPP。

如果不这样做，您将需要php_fileinfo.dll下载页面中的文件.zip，该文件与您安装PHP的ext文件相符将在php.ini文件夹中找到该文件。

将该文件复制到您的扩展程序文件夹中，修改[PHP_FILEINFO] extension=php_fileinfo.dll并添加此

composer

重启你的XAMPP，你就完成了。

安装扩展程序后，再次运行{{1}}命令。
