@PitaJ Thanks. I was seeing the same "Error: Cannot find module '@babel/runtime/core-js/object/create'" issue and deleting my node_modules directory and then runningnpm install ./nodebb setup
solved the problem for me.
I am on CentOS and was following the instructions, everything seemed fine, I run ./nodebb setup and I receive
