title: How can I re-upload package to pypi?
body: <p>I upload a package to pypi, but I got some trouble after upload, so I delete it completely, and I tried to re-upload, but there are some error after upload again:
  <code>
  HTTP Error 400: This filename has previously been used, you should use a different version.
  error: HTTP Error 400: This filename has previously been used, you should use a different version.
  </code>
  It seems pypi can track the upload activity, I delete project and account and upload again, but I can see the previous record. Why? 
  How can I solve the problem?</p>
