npm install express warnings

[danNL]

when running

sudo npm install -g express@2.5.8

i see the following warnings. are they issues that need to be resolved?

npm WARN package.json connect@1.9.2 No README.md file found!
npm WARN engine express@2.5.8: wanted: {"node":">= 0.4.1 < 0.7.0"} (current: {"node":"v0.8.16","npm":"1.1.69"})

Hi danNL, I have been away. It's nothing to worry about. express 2.5.8 expects a different version of Node.js. Once you have mastered the basics, it's relatively painless to upgrade express and the warnings will go away
