title: What is the path to yarn error log files?
body: <p>I'm migrating our gitlab CI script to yarn from npm and have the following line that saves npm error logs for 1 day:</p>
  
  <pre class="lang-yaml prettyprint-override"><code>artifacts:
    expire_in: 1 day
    paths:
      - /root/.npm/_logs/
  </code></pre>
  
  <p>My question is, <strong>what is the corresponding path for yarn error logs?</strong></p>
  
  <p>I have found the following two docs for yarn but neither says anything about error logs and searching the yarn docs yield nothing.</p>
  
  <ul>
  <li>Continuous Integration (<a href="https://yarnpkg.com/lang/en/docs/install-ci/#gitlab" rel="noreferrer">https://yarnpkg.com/lang/en/docs/install-ci/#gitlab</a>)</li>
  <li>Migrating from npm (<a href="https://yarnpkg.com/en/docs/migrating-from-npm" rel="noreferrer">https://yarnpkg.com/en/docs/migrating-from-npm</a>)</li>
  </ul>
