body: <p>I am trying to install dependencies using <code>pip3</code> command</p>
  
  <p>current scenario:</p>
  
  <pre><code>Dev$ which python
  /Users/Dev/anaconda/bin/python
  
  Dev$ which python3
  /usr/local/bin/python3
  
  
  Dev$ pip --version
  pip 10.0.1 from /usr/local/lib/python2.7/site-packages/pip (python 2.7)
  
  Dev$ pip3 --version
  -bash: /usr/local/bin/pip3: /usr/local/opt/python3/bin/python3.6: bad
