系统中缺少扩展gd - laravel composer Update

Kar*_*hik 33 php gd laravel laravel-5.2

我通过Composer(composer require barryvdh/laravel-dompdf)在Laravel Project中新安装了Dompdf .进入命令终端后回复以下错误.

Problem 1
    - dompdf/dompdf v0.7.0 requires ext-gd * -> the requested PHP extension gd is missing from your system.
    - barryvdh/laravel-dompdf v0.7.0 requires dompdf/dompdf ^0.7 -> satisfiable by dompdf/dompdf[v0.7.0].

打开你的php.ini并取消注释这一行:

;extension=php_gd2.dll

UPDATE

我猜,你正在使用ppa:ondrej php package(5.6),这让你对默认的ubuntu 14.04 php包(5.5.9)感到困惑.

要从ppa:ondrej安装php 5.6 gd库,您应该使用:

sudo apt-get install php5.6-gd

在安装缺少的依赖项之前，您需要检查系统上安装了哪个版本的 PHP。
