i am using Ubuntu 18.04 with all the pacage versions as mentioned in the above post and getting exactly the same error. As per the instructions , we have to install node js in Non SUDO mode!, but i installed using sudo, not sure if this is the source of the error. Appreciate any quick help to resolve this issue.
