title: eslint is running but not showing any lint errors/warnings
body: <p>I am using vscode with eslint.  The eslint console shows the following:</p>
  
  <pre><code>[Info  - 3:31:14 PM] ESLint server stopped.
  [Info  - 3:31:14 PM] ESLint server running in node v10.2.0
  [Info  - 3:31:14 PM] ESLint server is running.
  [Info  - 3:31:15 PM] ESLint library loaded from: 
  /usr/local/lib/node_modules/eslint/lib/api.js
  </code></pre>
  
  <p>So eslint appears to be loading and running.  However, there is a <code>.eslintrc</code> file in my project root that has rules and vscode is not showing me any linting errors.</p>
  
  <p>How do I debug this?</p>
