title: Node module giving no output - have I misunderstood how to install it?
body: <p>I'm trying to install and run the <code>geo2topo</code> node module, as described here:
  <a href="https://github.com/topojson/topojson-server#command-line-reference" rel="nofollow noreferrer">https://github.com/topojson/topojson-server#command-line-reference</a></p>
  
  <p>When I run it, I basically get no output - even -h gives no response, and no warnings or errors:</p>
  
  <pre><code>$ geo2topo -h
  $ geo2topo -V
  </code></pre>
  
  <p>I'm familiar with Linux sysadmin but not very familiar with node.</p>
  
  <p>I've done (on a Ubuntu 14.04 LTS box):</p>
  
  <pre><code>$ sudo apt-get install node npm
  $ sudo npm install topojson-server
  </code></pre>
  
  <p>as per:
  <a href="https://github.com/topojson/topojson-server#installing" rel="nofollow noreferrer">https://github.com/topojson/topojson-server#installing</a></p>
  
  <p>I've verified that it does seem to be present:</p>
  
  <pre><code>$ which geo2topo
  /usr/local/bin/geo2topo
  </code></pre>
  
  <p>and that the dependencies seem to be present:</p>
  
  <pre><code>$ npm -g ls
  /usr/local/lib
  └─┬ topojson-server@3.0.0
    └── commander@2.11.0
  </code></pre>
  
  <p>What am I doing wrong here?</p>
