setmask is not a Function

Question

I’ve had a big problem for a long time script that always worked, but today this giving "setmask is not a Function". I will send the call to be analyzed, also the script but warning that it may be a little long...

<script type="text/javascript">
    $(document).ready(function() {
       $('#txtCpf').setmask('cpf');
    });
</script>

<script src="https://cdn.rawgit.com/fabiomcosta/jquery-meiomask/master/di‌​st/meiomask.js"></script>
<script type="text/javascript">
     $(document).ready(function() {
        $('#txtCpf').setmask('cpf');
     });
</script>
<form>
    <input type="text" name="cpf" id="txtCpf" placeholder="CPF:049.253.241-24"/>
    <button value="enviar">
</form>
