title: what version of an npm package is installed?
body: <p>While preparing an app for release to the Google Play Store I discovered it was necessary to upgrade the Expo SDK in the project in order to successfully upload the app bundle (to target at least API level 29).  Once the Expo SDK was upgraded to 39.0.0 the upload worked fine.  However, while upgrading the Expo SDK a message in the terminal said</p>
  <blockquote>
  <p>The following packages were not updated.  You should check the READMEs
  for those repositories to determine what version is compatible with
  your new set of packages:<br>
  expo-linking</p>
  </blockquote>
  <p>I couldn't tell from the README which expo-linking version should be used with Expo SDK 39.0.0.</p>
  <p>After the Expo SDK upgrade, package.json shows this:</p>
  <pre><code>  &quot;dependencies&quot;: {
      &quot;expo&quot;: &quot;^39.0.0&quot;,
      &quot;expo-linking&quot;: &quot;~1.0.1&quot;,
  </code></pre>
  <p>Since the terminal message said expo-linking was not updated I <em>presume</em> package.json.dependencies.expo-linking didn't change either.</p>
  <p>Running <code>npm view expo-linking versions --json</code> reveals these versions exist:</p>
  <pre><code>[
    &quot;1.0.0-beta.1&quot;,
    &quot;1.0.0&quot;,
    &quot;1.0.1&quot;,
    &quot;1.0.2&quot;,
    &quot;1.0.3&quot;,
    &quot;1.0.4&quot;
  ]
  </code></pre>
  <p>Two questions:</p>
  <ol>
  <li>How/where can the installed version of expo-linking be found?</li>
  <li>I figured I'd install the latest version since the latest version of the Expo SDK is now installed for this project.  Could that cause problems?</li>
  </ol>
