title: Issues locating the right python
body: <p>First of all, I should say that I am not a python expert. </p>
  
  <p>I am struggling with different versions of python installed in my OS. I am running python v2.7 but after an update via brew, I got an issue. When I run a package called ilamb, I get the following error: </p>
  
  <blockquote>
    <p>/usr/local/bin/ilamb-run: bad interpreter:
    /usr/local/opt/python/bin/python2.7: no such file or directory</p>
  </blockquote>
  
  <p>The computer is somehow looking at local/opt folder, which I suspect was created from macports. I unfortunately deleted this folder because I was trying to standardize installations via brew and/or pip to avoid the kind of errors I am struggling with now. However, my python version is located at:</p>
  
  <pre><code>which python
  /usr/bin/python
  </code></pre>
  
  <p>How can I point to the right location?</p>
