Looks like something is going wrong in your package manager.
I haven't been able to reproduce your problem.
About node.js: yarn relies on it, and it will install it as a dependency if it does not exist on the system (your error message explains the install process hasn't been able to find it).

Maybe you should try to clean everything and try again:

• make sure yarn is not installled dnf remove yarn
• clean your cache dnf clean packages
• make sure everything is up to date dnf update
• try the installation process again

I have tried all these operations, but they are not working.
