The version of the running kernel must match the version of your kernel-devel package. In Oracle Linux 6.9, after a yum update, I found it wasn't booting into the new kernel by default. I didn't care about keeping the old version, so I booted into the new kernel using the menu at boot, then removed the old kernel with a verbose yum remove command with the full name of the old kernel package. I found the name of that package by running rpm -qa kernel* | sort. (That last command is also useful for checking that your kernel-devel package matches the running kernel.)

Updated with testing and additional details to make it work for CentOS.

I got errors that its not a directory. Note that it needs a slash at the end.. echo export KERN_DIR=/usr/src/kernels/uname -r/ >> ~/.bashrc

source ~/.bashrc to set KERN_DIR in the current environment without having to restart.

This was the right package to install, however recompiling the kernel modules required root privileges, and running something in root will lose your environment variables (including KERN_DIR). I instead did sudo -s followed by export KERN_DIR=/usr/src/kernels/XXX but I'm sure there's a better way to persist variables into sudo mode
