title: ImportError: No module named PySimpleGUI
body: <p>I am attempting to use PySimpleGUI to create a very simple GUI, but when I run the command &quot;python hello_world.py&quot; I get the error:</p>
  <pre><code>File &quot;hello_world.py&quot;, line 3, in &lt;module&gt;
      import PySimpleGUI as sg
  ImportError: No module named PySimpleGUI
  </code></pre>
  <p>I've run the command &quot;pip install PySimpleGUI&quot; and it says &quot;Successfully installed PySimpleGUI-4.55.1.&quot; I'm not sure what I'm missing here.</p>
  <p>Code snippet here:</p>
  <pre><code># hello_world.py
  
  import PySimpleGUI as sg
  
  sg.Window(title=&quot;Hello World&quot;, layout=[[]], margins=(100,50)).read()
  </code></pre>
