php - 您的系统缺少扩展名 gd - laravel composer Update

Question

我通过 Composer 在 Laravel 项目中新安装了 Dompdf(composer require barryvdh/laravel-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].
    - Installation request for barryvdh/laravel-dompdf ^0.7.0 -> satisfiable by barryvdh/laravel-dompdf[v0.7.0].

  To enable extensions, verify that they are enabled in those .ini files:
    - /etc/php/5.6/cli/php.ini
    - /etc/php/5.6/cli/conf.d/10-opcache.ini
    - /etc/php/5.6/cli/conf.d/10-pdo.ini
    - /etc/php/5.6/cli/conf.d/15-xml.ini
    - /etc/php/5.6/cli/conf.d/20-calendar.ini
    - /etc/php/5.6/cli/conf.d/20-ctype.ini
    - /etc/php/5.6/cli/conf.d/20-dom.ini
    - /etc/php/5.6/cli/conf.d/20-exif.ini

    - /etc/php/5.6/cli/conf.d/20-ftp.ini
    - /etc/php/5.6/cli/conf.d/20-gettext.ini
    - /etc/php/5.6/cli/conf.d/20-iconv.ini
    - /etc/php/5.6/cli/conf.d/20-json.ini
    - /etc/php/5.6/cli/conf.d/20-mbstring.ini
    - /etc/php/5.6/cli/conf.d/20-phar.ini
    - /etc/php/5.6/cli/conf.d/20-posix.ini
    - /etc/php/5.6/cli/conf.d/20-readline.ini
    - /etc/php/5.6/cli/conf.d/20-shmop.ini
    - /etc/php/5.6/cli/conf.d/20-simplexml.ini
    - /etc/php/5.6/cli/conf.d/20-sockets.ini
    - /etc/php/5.6/cli/conf.d/20-sysvmsg.ini
    - /etc/php/5.6/cli/conf.d/20-sysvsem.ini
    - /etc/php/5.6/cli/conf.d/20-sysvshm.ini
    - /etc/php/5.6/cli/conf.d/20-tokenizer.ini
    - /etc/php/5.6/cli/conf.d/20-wddx.ini
    - /etc/php/5.6/cli/conf.d/20-xmlreader.ini
    - /etc/php/5.6/cli/conf.d/20-xmlwriter.ini
    - /etc/php/5.6/cli/conf.d/20-xsl.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
