title: How does conda decide where to look for envs?
body: <p>I have ran <code>sudo chown -R $USER</code> on on <code>/opt/anaconda</code> folder in misguided attempt to fix <code>Permission denied</code> install errors, and now it refuses to find my envs in <code>~/.conda</code></p>
  
  <p>Instead it only sees the envs installed in <code>/opt/anaconda/4.2.0</code>. I tried <code>chown</code>ing back to <code>anaconda</code> user, but it still refuses to see envs in <code>~/.conda</code>. Does anyone know how conda decides where to look for envs/how to fix this?</p>
