嘗試安裝elfinder-laravel時出現作曲者錯誤

Question

我試圖在Laravel 5中安裝Laravel-elfinder。在它的GitHub page 中有一個循序漸進的教程，我遵循但它不工作。

我有XAMPP Web服務器在我的Windows PC上的Windows 8

基本上我要我的項目文件夾，並執行

composer require barryvdh/laravel-elfinder 

幾秒鐘後，我得到這個錯誤：

C:\xampp\htdocs\edent>composer require barryvdh/laravel-elfinder

有沒有人有任何想法我可以解決這個問題？

您通過作曲家安裝的所有公共軟件包均可在packagist.org中「搜索」。所以，如果你在packagist中搜索laravel-elfinder，最終你會得到at this page。

在那裏，你會看到一個列表需要，這意味着你看到的包依賴於另一個包，並且在安裝這些依賴之前你將無法使用你想要的包。但是，由於Composer非常聰明，它會嘗試爲您解決這些依賴關係。

就你而言，作曲家儘可能地解決了這個問題。基本上，barryvdh/laravel-elfinder取決於barryvdh/elfinder-flysystem-driver，反過來，取決於intervention/image。如果你去到後來的包，你會看到列表中需要這樣：

Requires
php: >=5.3.0
ext-fileinfo: *

我已經寫了這一切，所以你可以理解爲什麼在你的信息轉儲，您看到多個消息指出

intervention/image 2.1.3 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.

基本上，這意味着你需要在你的PHP安裝中啓用擴展fileinfo。

首先，打開你的php.ini並檢查你是否沒有擴展註釋。尋找這樣的事情：

#[PHP_FILEINFO] 
#extension=php_fileinfo.dll 

如果你找到它，取消（刪除#），並重新啓動XAMPP。

如果不這樣做，你需要從.zip文件，您PHP安裝相匹配的文件php_fileinfo.dll（你可以在PHP For Windows下載頁面獲得），你會發現在ext文件夾中的文件。

該文件到您的擴展文件夾中複製，編輯您的php.ini，並添加此

[PHP_FILEINFO] 
extension=php_fileinfo.dll 

重新啓動XAMPP，你就大功告成了。

當您安裝了擴展程序時，請再次運行composer命令。
