安装程序包时出错（安装失败，将./composer.json还原为其原始内容。）（Laravel管理程序包-Voyager）

我想安装一个laravel管理包-voyager 1.3版，所以当我运行这个cmd

$composer require tcg/voyager

时，我总是遇到这个错误，是关于composer.json文件的

Using version ^1.3 for tcg/voyager
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
    - tcg/voyager v1.3.0 requires intervention/image ^2.4 -> satisfiable by intervention/image[2.4.0, 2.4.1, 2.4.2, 2.4.3, 2.5.0, 2.5.1].
    - tcg/voyager v1.3.1 requires intervention/image ^2.4 -> satisfiable by intervention/image[2.4.0, 2.4.1, 2.4.2, 2.4.3, 2.5.0, 2.5.1].
   - intervention/image 2.4.3 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - intervention/image 2.4.2 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.

    - Installation request for tcg/voyager ^1.3 -> satisfiable by tcg/voyager[v1.3.0, v1.3.1].

  To enable extensions, verify that they are enabled in your .ini files:
    - C:\AppServ\php7\php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Installation failed, reverting ./composer.json to its original content.

这是composer.json文件： {

，你知道怎么解决吗？我的laravel版本：6.12

尝试在

php.ini

文件中启用

php\u fileinfo.dll

。只需从下面的行中删除

；

，然后重新启动服务器

;extension=php_fileinfo.dll

出于好奇：你读过那个错误消息吗？它很直接地告诉你该怎么做

;extension=php_fileinfo.dll
