無效的版本字符串“ 4.xx” + Laravel

Question

我正在嘗試將“ Asgardcms / Platform”軟件包安裝到Laravel 5.2。

安裝此軟件包時發現錯誤

[RuntimeException]                                                           
  Could not load package intervention/image in http://packagist.org: [Unexpec  
  tedValueException] Could not parse version constraint 4.x.x: Invalid versio  
  n string "4.x.x" 

 [UnexpectedValueException]                                                
  Could not parse version constraint 4.x.x: Invalid version string "4.x.x" 

我該如何解決該問題？
