title: Missing dependency in React Native
body: <p>I'm trying to build an app for Android but have been getting this error all afternoon: </p>
  
  <pre><code>A problem occurred configuring project ':app'.
  &gt; Could not resolve all dependencies for configuration ':app:_debugApk'.
     &gt; Configuration with name 'default' not found.
  </code></pre>
  
  <p>Just need to run some updates, I would think. So from the app's root I have tried: </p>
  
  <pre><code>yarn
  </code></pre>
  
  <p>and then</p>
  
  <pre><code>npm i
  </code></pre>
  
  <p>and </p>
  
  <pre><code>cup all -y
  </code></pre>
  
  <p>But the problem persists.</p>
  
  <p><strong>settings.gradle:</strong></p>
  
  <pre><code>rootProject.name = 'MyAppName'
  
  include ':react-native-firestack'
  project(':react-native-firestack').projectDir = new File(rootProject.projectDir, './node_modules/:react-native-firestack/android/')
  
  include ':react-native-fbsdk'
  project(':react-native-fbsdk').projectDir = new File(rootProject.projectDir, './node_modules/:react-native-fbsdk/android/')
  
  include ':app'
  </code></pre>
