How do I know where `yo` is running from? How to specify where it runs?

Question

In the beginning, I had yo and generator-angular installed on /usr/local/lib/node_modules (by doing the bad sudo npm install -g ...).

Then I read isaccs' advice on how to make npm and yo work without sudo, and modified his steps to make all the lines work. So I got yo and generator-angular installed on ~/.node/lib/node_modules as well.

Finally, suspecting that yo might be running from the original directory, I removed /usr/local/lib/node_modules. I created a brand new directory in "~/" and called yo angular in it, but was faced with: yo: command not found.

Is there a command that tells me from which directory yo is running from?

How can I tell yo that it should run from ~/.node/lib/node_modules?

1.Install nvm:

$ curl https://raw.github.com/creationix/nvm/master/install.sh | sh

2.Use nvm to install node and npm. Reopen your terminal and run the following commands in turn:

$ nvm install 0.10.26

$ npm install -g yo

$ npm install -g generator-angular

yo and generator-angular will be installed in ~/.nvm/v0.10.26/lib/node_modules. You can run them directly in the terminal now:

$ yo -v

3.Run which yo to find the directory yo is running from.
