devstack 安装openstack报错

安装systemd-python报错

报错：

Cannot find libsystemd or libsystemd-journal:

Package libsystemd was not found in the pkg-config search path.
Perhaps you should add the directory containing `libsystemd.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libsystemd' found

Package libsystemd-journal was not found in the pkg-config search path.
Perhaps you should add the directory containing `libsystemd-journal.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libsystemd-journal' found

#解决：

yum install python3-systemd
