My current version of node and npm is as follows

root@abhibhat-VirtualBox:/usr/src/socket.io# node -v
v0.7.7-pre
root@abhibhat-VirtualBox:/usr/src/socket.io# npm -v
1.1.10

root@abhibhat-VirtualBox:/usr/src/socket.io# 

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 1

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.
