Answer 1

Late to this party, but in the version of Bootstrap I'm using (v3.1.1) the class was 'progress-striped' (not 'progress-bar-striped' like the Docs say) and both it and the 'active' class had to be applied to the outer div:

<div class="progress progress-striped active">
    <div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100" style="width: 0%;">Some text</div>
</div>

Answer 2

<div class="progress">
  <div class="progress-bar progress-bar-striped progress-bar-animated" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: 75%"></div>
</div>

With this the progress animation will work.
