title: python setuptools entry point script can't find module
body: <p>I have the feeling I am missing some point here, and googling didn't get me far.</p>
  
  <p>I am using <code>setuptools</code> for a command line script. All goes fine but after installation my own files are not "seen" by the automatically generated script of the entry-point. Imagine the following case:</p>
  
  <p>file <code>a.py</code> contains:</p>
  
  <pre><code>a = 12
  </code></pre>
  
  <p>file <code>__main__.py</code> contains:</p>
  
  <pre><code>from a import a
  
  def main():
      print(a)
  
  if __name__ == '__main__':
      main()
  </code></pre>
  
  <p>file <code>__init__.py</code> is empty. File <code>setup.py</code> contains:</p>
  
  <pre><code>from setuptools import setup, find_packages
  
  setup(
      name='tep',
      packages=find_packages(),
      version='0.0.1',
      entry_points={
          'console_scripts': [
              'tep = tep.__main__:main'
          ]
      },
  )
  </code></pre>
  
  <p>all are properly located in the directory structure:</p>
  
  <ul>
  <li>test_entry_point
  
  <ul>
  <li>tep
  
  <ul>
  <li>__init__.py</li>
  <li>__main__.py</li>
  <li>a.py</li>
  </ul></li>
  <li>setup.py</li>
  </ul></li>
  </ul>
  
  <p>Locally all works well. But after installation:</p>
  
  <pre><code>sudo -H python setup.py install
  </code></pre>
  
  <p>and invoking from a different shell either by using <code>tep</code> or by using <code>python -m tep</code>, I get the following error:</p>
  
  <pre><code>ImportError: No module named 'a'
  </code></pre>
  
  <p>So the file <code>a.py</code> is not visible in the scope after installation . Any ideas?</p>
  
  <p>thanks.</p>
