ruby2.5-rubygem-unf.x86_64: W: hidden-file-or-dir /usr/lib64/ruby/gems/2.5.0/gems/unf-0.1.4/.travis.yml
The file or directory is hidden. You should see if this is normal, and delete
it from the package if not.

ruby2.5-rubygem-unf.x86_64: W: version-control-internal-file /usr/lib64/ruby/gems/2.5.0/gems/unf-0.1.4/.gitignore
You have included file(s) internally used by a version control system in the
package. Move these files out of the package and rebuild it.

ruby2.5-rubygem-unf.x86_64: E: env-script-interpreter (Badness: 9) /usr/lib64/ruby/gems/2.5.0/gems/unf-0.1.4/Rakefile /usr/bin/env rake
This script uses 'env' as an interpreter. For the rpm runtime dependency
detection to work, the shebang #!/usr/bin/env python  needs to be patched into
#!/usr/bin/python  otherwise the package dependency generator merely adds a
dependency on /usr/bin/env rather than the actual interpreter /usr/bin/python.
Alternatively, if the file should not be executed, then ensure that it is not
marked as executable or don't install it in a path that is reserved for
executables.
