title: Emacs Python Interpreter Is Not Set Correctly
body: <p>Fresh install of Linux Mint 18.3 Cinnamon.</p>
  
  <p>Also a fresh install of Gnu Emacs 24.5.1</p>
  
  <p>Also a fresh install of Anaconda3:</p>
  
  <pre><code> ~ $ conda -version
  usage: conda [-h] [-V] command ...
  conda: error: the following arguments are required: command
   ~ $ conda -V
  conda 4.4.10
   ~ $ python -V
  Python 3.6.4 :: Anaconda, Inc.
   ~ $ anaconda -V
  anaconda Command line client (version 1.6.9
  </code></pre>
  
  <p>Emacs has python-mode, python, and elpy installed, python code executed via <code>ctrl+Enter</code> is run with the executable in <code>/usr/bin/python</code> which is hopelessly out of date...2.7.2</p>
  
  <p>Executing <code>python</code> on the command line</p>
  
  <pre><code> ~ $ which python
  /home/user/anaconda3/bin/python
   ~ $ python
  Python 3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 18:10:19)
  </code></pre>
  
  <p>Also, <code>M-x elpy-config</code> yields an error: <code>neither easy install nor pip can be found</code> very strange, given <code>pip</code> was installed with anaconda3</p>
  
  <p>I don't know how to find what command elpy is using to run python or why elpy-config won't work, I assume that somewhere, it is hardcoded to the <code>/usr/bin</code> directory to look for all of the above executables, but no place I look indicates this. </p>
