  <p>After that I downloaded boost from here <a href="http://www.boost.org/users/history/version_1_66_0.html" rel="nofollow noreferrer">http://www.boost.org/users/history/version_1_66_0.html</a>
  Unziped and built it. Then built separetely boost.python. Now I have all of them in root directory. But when type <code>pip install bob</code> stil get the same error. I think python can't locate the boost directory. What should I do? Please help!</p>
