-I have the latest version of node, -I have updated npm

I suspect it might be a permissions error as running as administrator Any ideas?

Hi Dan,

It's typical now days for grunt/gems packages to require root permission when installing specific packages as they sometimes need to exist in the system executable bin which is protected by root, you can get around this by running the npm command as sudo like the below example.

sudo npm install grunt-contrib-copy --save-dev

Hope that helps.

It is a permissions error but sudo doesnt seem to work. Is it because I'm using windows 8? Do you know of an alternative work around? Thanks!
