Question

I'm new in bootstrap and web development. I'm trying to configure the menu bar using bootstrap, but I'm getting this error message:

Uncaught Error: Bootstrap's JavaScript requires jQuery at

My header is like this:

<meta charset=amp;quot;utf-8amp;quot;>
<meta http-equiv=amp;quot;X-UA-Compatibleamp;quot; content=amp;quot;IE=edgeamp;quot;>
<meta name=amp;quot;viewportamp;quot; content=amp;quot;width=device-width, initial-scale=1amp;quot;>

<script src="https://npmcdn.com/bootstrap@4.0.0-alpha.5/dist/js/bootstrap.min.js"></script>
 <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
 <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

Could you please help me? Thanks a lot!

It looks similar to this problem: Bootstrap won't detect jQuery 1.11.0 - Uncaught Error: Bootstrap's JavaScript requires jQuery

As @jeff_carey has mentioned, you have multiple versions of bootstrap and some appears before you included the jquery.

You could try:

<meta charset=amp;quot;utf-8amp;quot;>
<meta http-equiv=amp;quot;X-UA-Compatibleamp;quot; content=amp;quot;IE=edgeamp;quot;>
<meta name=amp;quot;viewportamp;quot; content=amp;quot;width=device-width, initial-scale=1amp;quot;>
<script src="https://npmcdn.com/tether@1.2.4/dist/js/tether.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<script src="js/wow.min.js"></script>

or

<meta charset=amp;quot;utf-8amp;quot;>
<meta http-equiv=amp;quot;X-UA-Compatibleamp;quot; content=amp;quot;IE=edgeamp;quot;>
<meta name=amp;quot;viewportamp;quot; content=amp;quot;width=device-width, initial-scale=1amp;quot;>
<script src="https://npmcdn.com/tether@1.2.4/dist/js/tether.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="https://npmcdn.com/bootstrap@4.0.0-alpha.5/dist/js/bootstrap.min.js"></script>
