title: Linting in Visual Studio Code not working
body: <p>I have been using VSC (Version 1.19.1 for Mac) including the official Python extension (0.9.1) for a couple of month now. As I left most of the configuration unchanged, I have been using Pylint for linting.</p>
  
  <p>Until a couple of weeks ago everything was fine, now linting doesn't work anymore.</p>
  
  <p>An example would be:</p>
  
  <pre class="lang-python prettyprint-override"><code>def test(x):
  return x
  </code></pre>
  
  <p>Here I would normally get an indention error shown by Pylint which doesn't happen anymore.</p>
  
  <p>I have re-installed the Python extension and then re-installed Visual Studio Code, nothing worked. Can anyone help me?</p>
  
  <p>I run MacOS 10.13.1, Python 3.6. and Pylint 1.8.1. My user settings for VSC are:</p>
  
  <pre><code>"editor.rulers": [
  99
  ],
  "files.insertFinalNewline": true,
  "workbench.activityBar.visible": true,
  "files.trimTrailingWhitespace": true,
  "editor.minimap.enabled": false,
  "explorer.confirmDragAndDrop": false
  </code></pre>
