title: Module Not Found Error in Python 3.6 on windows command prompt
body: <p>I have created a project like the below one:</p>
  
  <pre><code>project
  |
  | --package1
  |      |
  |      -- __init__py
  |      --module1.py
  |
  | --package2
         |
         --__init__.py
         --module2.py
  </code></pre>
  
  <p>I want to import module1 into module2, (from package1 import module1)</p>
  
  <p>In PyCharm everything is just working fine. But when I try to open the file "module2.py" from Windows10 command prompt I get  <code>ModuleNotFoundError: No module named 'module1'</code>. </p>
  
  <p>I was looking for the solution but not a single one worked.
  I'm using python 3.6 and I have set environment variable <code>PYTHONPATH = I:\project\package1</code></p>
