title: Emacs M-x term can't find node/coffee
body: <p>I've been plonking around on mac-emacs, and I've <code>M-x install-package</code>-d coffee-mode. I decided to try out the <code>coffee-compile-file</code> command, but when I ran it, it failed, complaining that it couldn't find the <code>coffee</code> command.</p>
  
  <p>So, I open up terminal, on ZSH and Bash. <code>coffee</code> and <code>node</code> run fine on both. So, split my emacs screen, plink out <code>M-x term</code>, let bash load, and type <code>coffee</code>:</p>
  
  <pre><code>bash-3.2$ coffee 
  bash: coffee: command not found
  </code></pre>
  
  <p>Odd. I tried the same for node and npm.</p>
  
  <pre><code>bash-3.2$ node
  bash: node: command not found
  bash-3.2$ npm
  bash: npm: command not found
  </code></pre>
  
  <p>My question is, <em>why</em> does this happen only on <code>M-x term</code>, and how can I fix it.</p>
