Run “yum repolist all” to see the repos you have.

当前配置文件：

[root@localhost yum.repos.d]# cat yumsource.repo        
[centos7]
name=centos7
baseurl=file:///source/              #  本地YUM目录绝对路径
gpgcheck=0
enabled=1                            #  1表示启用，0表示关闭

[root@localhost yum.repos.d]# vim yumsource.repo

问题原因：repo配置文件中存在#的注释信息，删除即可。

清除缓存，重新建立yum索引信息。
