在云端服务器上以centos 6.7安装elastix

Question

我想在我的服务器上安装elastix 2.5。

yum install -y elastix

然后我收到了这个错误

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

似乎错误说需要降级每个包。但它是如此非常冲突，特别是在卷曲上。 是否有任何可能的解决方案来解决错误或任何其他方式？我只想在centos 6.7上安装elastix。 有人可以提供帮助吗？ 提前致谢。
