当我尝试部署我的laravel项目并执行php composer.phar安装时,我得到了这个恼人的错误.我通过git用git clone拉入了我的项目.当我浏览我的域名时,我希望看到我的应用程序:).我已经安装了正确版本的apache,mysql和php.一切都在运行.

编辑如何安装gd&dom？

当我做yum install php-gd我得到这个错误:错误:php56w-与php-common-5.4.16-36.el7_1.x86_64的常见冲突

首先运行以下两个命令来安装 PHP 5.5 的 RPM：

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

然后运行：

yum install php-gd
