title: install pip3 for conda
body: <p>Python2.6 was installed by default in my old centos server. Now I want to create a Python3 environment to install python3 specific module by conda  </p>
  
  <pre><code>conda create -n py3 python=3.5.3
  source activate py3
  </code></pre>
  
  <p>After activate the py3, I try to install hovercraft by <code>pip3 install hovercraft</code>, the shell tells "command not found: pip3".  At first I thought pip3 was installed with Python3, but the result was not the case.<br>
  So I think I can install it manually. The package gzip file was downloaded from <a href="https://pypi.python.org/packages/18/ce/a39cdc0c467098a1c274b6cd3a62115f831340e45731d64bc7cc08fcdfc6/hovercraft-2.3.tar.gz" rel="noreferrer">python package index</a>, and install by <code>conda install --file hovercraft-2.3.tar.gz</code>. But it doesn't work.<br>
  Now I have two problems:</p>
  
  <ol>
  <li>how to install pip3 for virtual-env create by conda?    </li>
  <li>Is it possible to install python package index downloaded package locally in conda?</li>
  </ol>
