How did you install it ?
sudo apt install nodejs
Or did you install it manually and installed a 64bit on a 32 bit OS? This would explain the "Illegal instruction" error.

I have installed NodeJS with sudo apt install nodejs many times without hiccup.
The only thing I can think of is a corrupted file system.
Check your logs as well.
