模块依赖问题

 问题 1: conflicting requests
  - nothing provides module(perl:5.26) needed by module perl-DBD-SQLite:1.58:8010020191114033549:073fa5fe-0.x86_64
 问题 2: conflicting requests
  - nothing provides module(perl:5.26) needed by module perl-DBI:1.641:8010020191113222731:16b3ab4d-0.x86_64

大意是说找不到依赖，这2个依赖默认是安装了的，只是未启用，启用即可：

yum module enable perl:5.26
