title: What does the ELIFECYCLE Node.js error mean?
body: <p>What does ELIFECYCLE mean?</p>
  
  <p>Here's my app code: <a href="https://gist.github.com/samholmes/388ca4552c5936b52c5d">https://gist.github.com/samholmes/388ca4552c5936b52c5d</a></p>
  
  <p>When I run the 'blast-emails' command, it will run for a while until shortly crashing with the error:</p>
  
  <pre><code>npm ERR! Linux 3.2.0-4-amd64
  npm ERR! argv "/root/.nvm/versions/io.js/v1.6.1/bin/iojs" "/root/.nvm/versions/io.js/v1.6.1/bin/npm" "run" "live"
  npm ERR! node v1.6.1
  npm ERR! npm  v2.7.1
  npm ERR! code ELIFECYCLE
  npm ERR! emailer@0.0.0 live: `NODE_ENV=production node app.js`
  npm ERR! Exit status 137
  npm ERR! 
  npm ERR! Failed at the emailer@0.0.0 live script 'NODE_ENV=production node app.js'.
  npm ERR! This is most likely a problem with the emailer package,
  npm ERR! not with npm itself.
  npm ERR! Tell the author that this fails on your system:
  npm ERR!     NODE_ENV=production node app.js
  npm ERR! You can get their info via:
  npm ERR!     npm owner ls emailer
  npm ERR! There is likely additional logging output above.
  
  npm ERR! Please include the following file with any support request:
  npm ERR!     /apps/emailer/npm-debug.log
  </code></pre>
  
  <p>The <code>npm-debug.log</code> file is also included in the gist.</p>
  
  <p>I'm looking for one of two answers: What does ELIFECYCLE mean? (or) Why am I getting the error in my application code?</p>
