npm ERR! code EPEERINVALID

Question

I'm new here. I am getting an - npm ERR! code EPEERINVALID (details below), and I am currently running the following:

• nvm 0.32.1
• npm 2.15.9
• node v4.5.0
• grunt-cli v1.2.0
• grunt v0.4.5

And, when doing a package or I guess a module upgrade I am getting the following error...

I am confused as to what to do because my version of grunt is >= the version it's asking for. I have done the following:

• npm cache clean
• rm node_modules
• re-install node/npm via nvm

I am using nvm, but I did have an issue previously with npm not being found and I did an update not using nvm. Since that time I did try to clean things up and re-install with nvm - not sure if this is presenting a problem. Any assistance/advice here would be great. Thanks!
