Below is the error I keep getting. It seems to indicate a "post-install" issue with yodoctor. Sadly yodoctor is the advice given by the yeoman team to help with this issue. I have other node_modules installed (bower, grunt, typescript).
sh: yodoctor: command not found

This error is generally caused because someone used sudo at some point and messed up their npm package directory permissions. As a rule of thumb, never ever use sudo.
So how can you fix it? Here's a couple troubleshooting points:
- Make sure you update npm to the latest version (
npm install -g npm). npm 2.x had some race conditions that would try to runyodoctorbefore it is installed. - Make sure the global npm module folders is chown/chmod to your user.
- Make sure npm module binaries is in your PATH.
- If nothing works, then you can force install it by running
npm i -g yeoman-doctor && npm i -g yo- but that really is a last recourse solution.

Just the following command would do the trick:
sudo npm install -g yo
if not, find where yo is, add it to the path as follows:
export PATH="$PATH:<path where yo is installed>"
