[Starlingx-discuss] build-pkgs failed when building iso

Hi everyone, I'm trying to build starlingx iso by following the guide step by step and got some error messages. When execute command "build-pkgs", the message "build-srpm-parallel --std failed with rc=1" was printed. When execute command "generate-cgcs-tis-repo", the message "find: ‘//localdisk/loadbuild/root/starlingx/rt/rpmbuild/RPMS’: No such file or directory" was printed. When execute command "build-iso", the message " Error -- could not install all explicitly listed packages" was printed. The logs attached with this email are the output of those command. Anyone knows what these error messages meam or the building details? thanks
