找不到任何解决方案。更新到Ubuntu至17.10，在那里它运行良好。

你可以在Ubuntu中搜索任何软件包，执行

sudo-apt-cache-search-libmagickwand-dev

，如果你找到你要找的软件包，那么就执行

sudo-apt-get-install-libmagickwand-dev

，安装它

安装所有未满足的依赖项应该可以解决这个问题，执行下面的命令升级任何缺少的包总是很有帮助的

sudo apt-get upgrade && sudo apt-get update

您应该可以安装<代码> RMAGICK < /代码>，没有任何问题。

您可以考虑，这实际上是一个替换的掉线，安装和资源使用都得到了改善。
