title: Launch yarn run script launch error whereas pure command is working (React Native Project)
body: <p>I added a script command in my package.json as following :</p>
  
  <pre><code>"ios": "sh config.sh &amp;&amp; react-native run-ios"
  </code></pre>
  
  <p>This command is working fine when i do it <strong>without</strong> yarn.</p>
  
  <p>But when i try to execute it <strong>with</strong> yarn (<em>yarn run ios</em> or <em>yarn ios</em>)... The command is well executed but Metro bundler is failing with this given error :</p>
