title: conda and pip not working at all
body: <p>I am on OS X 10.11.2, Anaconda Python 2.7.10.</p>
  
  <p>I was installing some dependencies, and suddenly, my <code>conda</code> command started not working at all. Many people suggest <code>conda install python=2.7.10</code> but when I try that (or any command, even just <code>conda</code>) I get:</p>

  <p>How can I repair <code>conda</code>, without using <code>conda</code> itself (as I can't)?</p>
  
  <p><strong>UPDATE:</strong> I've completely uninstalled and reinstalled Anaconda. It still gives the same error. I've tried <code>pip</code> and it also fails with the same error. I verify it's Anaconda's pip as <code>which pip</code> returns <code>/Users/Can/anaconda2/bin/pip</code>. Why is Anaconda broken?</p>
