yum - 无法安装 libffi-devel

Question

我尝试在 RHEL 上安装 libffi-devel，但是当我尝试时收到此消息:

Transaction Check Error:
  package libffi-3.0.5-1.el5.6.z.x86_64 (which is newer than libffi-3.0.5-1.el5.i386) is already installed

我正在运行此命令:

sudo yum install -y libffi-devel

这是命令的完整输出:

您的系统上似乎已经安装了 libffi-3.0.5-1.el5.6.z.x86_64 版本。使用命令检查并先删除rpm。

rpm -qa | grep libffi
rpm -e <rpm from the above>

然后尝试使用以下命令进行安装:

sudo yum install -y libffi libffi-devel
