Hi Team,

It sounds like you have a _io.so file that was compiled against a different python version, from that which is attempting to use it.

Using python from an SCL as your ansible_python_interpreter is not just an easy 1 and done, by using the correct path. An SCL sets things like LD_LIBRARY_PATH and such when you enable it, that is not achieved by simply calling the binary in its place.

It looks like you are using localhost, which I will assume is “implicit localhost”[1] which automatically selects the python interpreter used by the playbook process, but since that work happens in a fork, I imagine it loses the SCL env vars required to use that SCL.

Overall, I’d probably recommend not using an SCL. Otherwise, you are going to have to jump through some hoops that are going to require that you better understand what needs to be done.

Hi Matt,
