title: How to fix spacemacs importmagic and/or epc not found?
body: <p>I use spacemacs config to open a python file.</p>
  
  <p>emacs: 25.3.1<br>
  spacemacs: 0.300.0<br>
  platform: osx</p>
  
  <p>I add python layer in <code>dotspacemacs-configuration-layers</code>,
  besides I use miniconda to control my python envs with <code>(setenv "WORKON_HOME" "~/miniconda3/envs")</code> in <code>dotspacemacs/user-init</code>.</p>
  
  <p>Then I run into this problem(copy from <em>Messages</em>) when I open a python file:</p>
  
  <pre><code>Importmagic and/or epc not found. importmagic.el will not be working.
  </code></pre>
  
  <p>Tried to solve this situation from discussion at <a href="https://github.com/syl20bnr/spacemacs/issues/10145" rel="noreferrer">spacemacs#10145</a>
  by add </p>
  
  <pre><code>(require 'pyvenv)
  (pyvenv-activate DIRECTORY)
  </code></pre>
  
  <p>into my <code>dotspacemacs/user-config</code> but with no lucky.</p>
  
  <p>Hope someone could give me some advice, thank you!</p>
