Hi,

I'm trying to install Keystone.js which as a pre-requisite, requires installation of both Node and MongoDB, so I followed the following posts to do so:

https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-an-ubuntu-14-04-server
https://www.digitalocean.com/community/tutorials/how-to-install-mongodb-on-ubuntu-14-04

This has installed a 'stable' version of NodeJS on my server. However, when I then install keystone with the following commands:

npm install -g generator-keystone

and create a directory:

mkdir test-directory
cd test-directory

I'm required to run the generator

yo keystone

which returns:

yo: command not found

Searching around, it's cleary that perhaps my PATH wasn't exported:

export PATH="$PATH":~/.node/bin

but that doesn't fix the issue. So I decided to follow the advice of the last post here instead, which uninstalls grunt and yo, and reinstalls yo:

http://stackoverflow.com/questions/24026166/yo-command-not-found

But after uninstalling both packages, I'm now faced with this error upon reinstalling just yo:

sh: 1: node: not found
npm WARN This failure might be due to the use of legacy binary "node"
npm WARN For further explanations, please read
/usr/share/doc/nodejs/README.Debian

How do I resolve this?

For reference, the Keystone documentation is here for installation - http://keystonejs.com/getting-started/

It is probably related to a shift in commands from one version of node to the other, so perhaps I should be installing a specific version of node instead?
