PHP version 5.4.16不能安装thinkPHP5.

笔者本机安装了thinkPHP5.1的项目，通过git传送到CentOS上时，各种错误，百思不得其解。

后来，干脆直接在阿里云CentOS安装，出现了这样的错误：

[Abble@centos7 html]$ composer config -g repo.packagist composer https://packagist.phpcomposer.com
[Abble@centos7 html]$ composer create-project topthink/think=5.1.12 test


  [InvalidArgumentException]
  Could not find package topthink/think with version 5.1.12 in a version installable using your PHP version 5.4.16.
