Getting started - errors on first time run

[alternaterealben]

Hi,
I'm trying to use SecGen but it's having issues. The project builds correctly in Ubuntu 20.04, but running the command ruby secgen.rb run fails with the following error. It's the most recent version of SecGen, and a clean system with nothing else installed.

I can see that there is a similar existing issue, but it seems to be different? I don't want to co-opt it.

Any help would be appreciated. Thanks.
