npm install fail

[a-lucas]

Using node.js 0.12.14

I have this grunt error:

npm ERR! Darwin 15.4.0
npm ERR! argv "/Users/antoinelucas/.nvm/versions/v0.12.14/bin/node" "/Users/antoinelucas/.nvm/versions/v0.12.14/bin/npm" "install"

npm ERR! peerinvalid Peer [email protected] wants grunt@>=0.4.0

my grunt/grunt-cli version:

grunt --version
grunt-cli v0.1.13
grunt v0.4.5

[cv711]

Same here using node.js 4.4.2

Adding "grunt": "~0.4.5" as a dependency in package.json seems to fix it.
