我用tp5做了一个项目，部署到了云服务器上【CentOs 6.5】,我安装lamp环境时yum获取的php是5.3的，因为框架需要，所以我就升级php内核到5.5.3，但是发现其缺少gd库，在低版本的php中只需在php.ini中打开extension = php_gd2就可以了，但是我发现在5.5中不行，于是我尝试安装gd库，可是我换了好几种方式也安装不了gd扩展，而且其缺少的依赖全是5.3的包，不知为何，请高手帮忙解决。

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
