title: VS Code doesn't recognize pep8
body: <p>To use linting for Python, I configured <code>VS Code</code> like this:</p>
  
  <pre><code>"python.linting.enabled": true,
  "python.linting.pylintEnabled": false,
  "python.linting.pep8Enabled": true,
  "python.linting.lintOnTextChange": true,
  "python.linting.lintOnSave": true
  </code></pre>
  
  <p>Then I opened a <code>*.py</code> file and added an unnecessary space and saved, then I got an error: <code>Linter pep8 is not installed</code>.</p>
  
  <p>But I already installed <code>pep8</code>. And by using VS Code console I can find the <code>pep8</code>.</p>
  
  <h3>With VS Code console</h3>
  
  <pre><code>/usr/bin/python -m pip install pep8
  loading ~/.zshrc_osx
  ironsand@macbook ~ % /usr/bin/python -m pip install pep8
  /usr/bin/python: No module named pip
  ironsand@macbook ~ % which python
  /usr/bin/python
  ironsand@macbook ~ % which pep8
  /usr/local/bin/pep8
  ironsand@macbook ~ % pep8 --version
  1.7.0
  ironsand@macbook ~ % which python
  /usr/bin/python
  ironsand@macbook ~ %
  </code></pre>
  
  <p>Maybe I installed <code>pep8</code> by using <code>pip2</code> that is installed <code>brew</code>.</p>
  
  <h3>With OS Console(iTerm2)</h3>
  
  <pre><code>python --version
  Python 2.7.10
  ironsand@macbook ~ % /usr/local/bin/pip2 install pep8
  Collecting pep8

  Successfully installed pep8-1.7.0
  </code></pre>
  
  <p>What am I doing wrong?</p>
  
  <h3>Plugins</h3>
