Uncaught ReferenceError: Meteor is not defined
<p>I'm following a tutorial to create a Meteor app and I've been having the same error regarding different things in the developer console.</p>

<pre><code>&gt; Meteor.users.find().count();
VM2034:1 Uncaught ReferenceError: Meteor is not defined(…)(anonymous function) @ VM2034:1

&gt; Session.set('pageTitle', 'A different title');
VM2035:1 Uncaught ReferenceError: Session is not defined(…)
</code></pre>

<p>From researching the problem, the 2 solutions that come up are: (1) doing </p>

<pre><code>meteor add session
</code></pre>

<p>which I have done; (2) updating the Meteor version but I am running Meteor 1.3.3. Neither works.</p>

<p>EDIT: After doing <code>meteor update</code>, the Meteor error disappeared once but came back the second time I tried a command based on Meteor. </p>

<p>Any idea on how to solve this?</p>
