title: mypy cannot find module 'dropbox'
body: <p>I have a <a href="https://github.com/blokeley/backup_dropbox" rel="nofollow noreferrer">small codebase to back up Dropbox Business files</a>, and am trying to use <a href="http://mypy-lang.org/" rel="nofollow noreferrer">mypy</a> to help me use the rather unpythonic <a href="https://github.com/dropbox/dropbox-sdk-python" rel="nofollow noreferrer">Dropbox Python SDK</a>.</p>
  
  <p>I have installed mypy, and it is working.</p>
  
  <p>However, mypy raises a warning for the following line:</p>
  
  <pre><code>import dropbox
  </code></pre>
  
  <p>The warning is "Cannot find module named 'dropbox'".</p>
  
  <p>It seems that Dropbox's SDK generator, called Stone, should <a href="https://github.com/dropbox/stone/blob/master/stone/target/python_type_stubs.py" rel="nofollow noreferrer">generate compatible stub files</a> (which in this case would be called <code>dropbox.pyi</code>).</p>
  
  <p>But there is no <code>dropbox.pyi</code> in <code>site-packages/dropbox</code>, where mypy would look for it.</p>
  
  <p>How can I get type checking for the <code>dropbox</code> package working?</p>
  
  <p>Thanks in advance.</p>
