Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Installation request for intervention/image 2.3.x-dev -> satisfiable by intervention/image[2.3.x-dev].
- intervention/image 2.3.x-dev requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
Problem 2
- Installation request for intervention/image dev-master -> satisfiable by intervention/image[dev-master].
- intervention/image dev-master requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
To enable extensions, verify that they are enabled in those .ini files:
- /usr/local/php/etc/php.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
解决：
安装PHP程序的时候，提示The fileinfo extension is required.，缺少fileinfo 扩展，因为LNmpA没有自行开启，所以需要我们手工去开启fileinfo 扩展。
方法如下：
第一步：找到lnmpa安装源位置：
cd /lnmp1.3-full/src/php-5.6.9/ext/fileinfo/
第二步：
/usr/local/php/bin/phpize
返回类似下面的信息：
Configuring for:
PHP Api Version: 20131106
Zend Module Api No: 20131226
Zend Extension Api No: 220131226
phpize是什么东西呢？
php官方的说明：http://php.net/manual/en/install.pecl.phpize.php
phpize是用来扩展php扩展模块的，通过phpize可以建立php的外挂模块，比如你想在原来编译好的php中加入memcached或者ImageMagick等扩展模块，可以使用phpize。
第三步：
./configure --with-php-config=/usr/local/php/bin/php-config
make && make install
返回类似下面信息：
Build complete.
Don't forget to run 'make test'.
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/
表明安装成功了。
第四步：
/usr/local/php/etc/php.ini 添加扩展：
extension=fileinfo.so
/etc/init.d/php-fpm restart
