title: Firebase Admin Nodejs cannot find module service_account.json
body: <p>I start my node with "node firebasedb.js". My firebasedb.js contains this code:</p>
  
  <pre><code>var admin = require("firebase-admin");
  
  var serviceAccount = require("service_account.json");
  
  // Initialize Firebase
  var config = {
      credential: admin.credential.cert(serviceAccount),
      apiKey: "&lt;api key&gt;",
      authDomain: "&lt;auth domain&gt;",
      databaseURL: "&lt;database url&gt;",
      storageBucket: "&lt;storage bucket&gt;",
  };
  
  admin.initializeApp(config);
  </code></pre>
  
  <p>When I run node, I am in the directory where the .json file exists.
  But it says </p>
  
  <pre><code>Error: Cannot find module 'service_account.json'
  </code></pre>
