My current version of node and npm is as follows

Is it that my node version is higher than the supported upper limit? If so what is the solution?

I am clueless as to how to proceed from here. Please !!HELP!!

Answer

npm -f install socket.io just solved the issue. I also checked package.json and there seems to be no upper limit “engines”: { “node”: “>= 0.4.0” }. Strangely I also had to issue npm -g list prior to issuing npm -f install, but how it solved the problem I am clueless.
