今天安装laravel mews/captcha来实现 Laravel 中的验证码功能。
我的系统环境

CentOS Linux 7.4.1708

没想到居然安装不上，具体如下

[root@VM_0_4_centos larabbs]# composer require mews/captcha

To enable extensions, verify that they are enabled in your .ini files:
  - /www/server/php/71/etc/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.

之后才知道是因为没有安装php扩展fileinfo的原因，那么下面就来安装一下：
首先查找fileinfo源码放在哪里

[root@VM_0_4_centos larabbs]# find / -name fileinfo
/www/server/php/72/src/ext/fileinfo

进入目录

cd /www/server/php/72/src/ext/fileinfo

phpize是编译PHP扩展的工具，主要是根据系统信息生成对应的configure文件
开始扩展的安装：

[root@VM_0_4_centos fileinfo]# find / -name phpize
/usr/bin/phpize
/www/server/php/71/bin/phpize
/www/server/php/72/src/scripts/phpize
/www/server/php/72/bin/phpize

初始化扩展安装

[root@VM_0_4_centos fileinfo]# /www/server/php/72/bin/phpize
Configuring for:
PHP Api Version:         20170718
Zend Module Api No:      20170718

编译并安装

[root@VM_0_4_centos larabbs]# make && make install

然后修改php.ini文件，找到下面这一行

;extension=fileinfo

分号去掉即可,然后安装 mews/captcha 扩展包

[root@VM_0_4_centos larabbs]# composer require mews/captcha
