[wdh@izhp3flliiu1w www]$ composer create-project laravel/laravel --prefer-dist
    PHP Warning:  Module 'zip' already loaded in Unknown on line 0
    Installing laravel/laravel (v5.0.22)
      - Installing laravel/laravel (v5.0.22): Loading from cache
    Created project in /www/wwwroot/default_online/www/laravel
    Loading composer repositories with package information
    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 laravel/framework v5.0.16 -> satisfiable by laravel/framework[v5.0.16].
        - laravel/framework v5.0.16 requires ext-mcrypt * -> the requested PHP extension mcrypt is missing from your system.
    
      To enable extensions, verify that they are enabled in your .ini files:
        - /etc/php.ini
        - /etc/php.d/curl.ini
        - /etc/php.d/dom.ini
        - /etc/php.d/fileinfo.ini
        - /etc/php.d/gd.ini
        - /etc/php.d/intl.ini
        - /etc/php.d/json.ini
        - /etc/php.d/mbstring.ini
        - /etc/php.d/pdo.ini
        - /etc/php.d/pdo_sqlite.ini
        - /etc/php.d/phar.ini
        - /etc/php.d/posix.ini
        - /etc/php.d/sqlite3.ini
        - /etc/php.d/sysvmsg.ini
        - /etc/php.d/sysvsem.ini
        - /etc/php.d/sysvshm.ini
        - /etc/php.d/wddx.ini
        - /etc/php.d/xmlreader.ini
        - /etc/php.d/xmlwriter.ini
        - /etc/php.d/xsl.ini
        - /etc/php.d/zip.ini
      You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

### **报错原因：centos 中 php缺少 mcrypt扩展** ###
