setmask is not a function

I have a big problem for a long time, I use a script that always worked, but today it is giving setmask is not a function . I will send the call to be parsed, also the script but notice 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><scripttype="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>
