centos8.4使用本地yum源安装提示：Error: No available modular metadata for modular package

安装modulemd-tools

modulemd-tools安装和使用详细过程参考官方文档https://github.com/rpm-software-management/modulemd-tools。

更换centos8.4 yum源

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo
yum clean all && yum makecache

安装modulemd-tools

yum install modulemd-tools

 

构建module metadata

假设本地源已经存在，比如/opt/zfs是一个存放zfs相关的一系列rpm包的本地yum源目录。该目录已经通过createrepo命令创建好。那么该目录下一定会生成一个repodata目录，然后依次执行以下命令即可。

cd /opt/zfs
repo2module ./
createrepo_mod ./

其中，repo2module ./会在当前目录下生成一个modules.yaml文件，createrepo_mod ./会在repodata目录下生成一个以modules为结尾的文件。
