Getting error when trying to install compass npm ERR! Cannot read property 'length' of undefined

Question

I'm trying to install compass onto my hosting server and I keep getting the above error fed back to the shell.

npm ERR! Cannot read property 'length' of undefined

I've install node, grunt, contrib-watch, and contrib-uglify after some work arounds. The last dependency I need is compass.

I don't see any errors in the logs until I get to the very bottom:

4924 error Linux 3.12.18-clouder0
4925 error argv "/home/joshuag3/bin/node" "/home/joshuag3/bin/npm" "install" "grunt-contrib-watch" "--save-dev"
4926 error node v4.4.1
4927 error npm  v2.14.20
4928 error code EPEERINVALID
4929 error peerinvalid The package [email protected] does not satisfy its siblings' peerDependencies requirements!
4929 error peerinvalid Peer [email protected] wants grunt@~0.4.0
4930 verbose exit [ 1, true ]

I am very very new to node and this type of thing. If there is a solution please overly explain.

Answer 1

Open your cmd and Go to your root User folder such as C:\Users\User and run npm install -g npm@latest

this will update your npm to the latest version. Try your install again and should work fine now.

Additionally, you can use npm audit fix after the npm install -g npm@latest
