title: NODE_ENV=development set in .bash_profile but undefined when using it in code
body: <p>My <code>~/.bash_profile</code> content:</p>
  
  <pre><code>export MONGO_PATH=/usr/local/mongodb
  export NODE_ENV=development
  export PATH=$PATH:$MONGO_PATH/bin
  ### Added by the Heroku Toolbelt
  export PATH="/usr/local/heroku/bin:$PATH"
  
  # {{{
  # Node Completion - Auto-generated, do not touch.
  shopt -s progcomp
  for f in $(command ls ~/.node-completion); do
    f="$HOME/.node-completion/$f"
    test -f "$f" &amp;&amp; . "$f"
  done
  # }}}
  </code></pre>
  
  <p>However in my app.js code my process.env.NODE_ENV is undefined. I've searched for my issue but only find how to set it and I seemed to have followed "how to" correctly. Am I missing something?</p>
