只需运行:

yum install rpm-build

看来，如果 rpmbuild 命令不可用，setuptools 会回退到使用rpm"命令，它(据我所知)很久以前就内置了 rpmbuild 功能，但此后已被分离.因此，安装 rpm-build 包会使 rpmbuild 命令可用，并且 setuptools 在构建包时会使用它.

It appears that if the rpmbuild command is not available, setuptools falls back to usig the "rpm" command, which (as I understand it) had the rpmbuild functionality built in long, long ago but has since beeen separated. So, installing the rpm-build package makes the rpmbuild command available and setuptools uses it when it is building your package.
