title: dotenv import in python3.7 (MacOS)
body: <p>dotenv installed, to be sure I check this by calling pip3 and pip3.7, despite that it's same</p>
  
  <pre><code>(env) slonocomp:-wrapper oleg$ pip3.7 freeze | grep dotenv
  django-dotenv==1.4.2
  python-dotenv==0.11.0
  (env) slonocomp:wrapper oleg$ pip3 freeze | grep dotenv
  django-dotenv==1.4.2
  python-dotenv==0.11.0
  (env) slonocomp:wrapper oleg$
  </code></pre>
  
  <p>version of p3 and p3.7 actualy the same </p>
  
  <pre><code>(env) slonocomp:wrapper oleg$ python3 -V
  Python 3.7.4
  (env) slonocomp:wrapper oleg$ python3.7 -V
  Python 3.7.4
  </code></pre>
  
  <p>But when I try to import dotenv in interactive mode (for demonstration) I got differences</p>
  
  <pre><code>(env) slonocomp:wrapper oleg$ python3
  Python 3.7.4 (default, Oct 12 2019, 18:55:45)
  [Clang 10.0.0 (clang-1000.11.45.5)] on darwin
  Type "help", "copyright", "credits" or "license" for more information.
  &gt;&gt;&gt; import dotenv
  &gt;&gt;&gt;
  (env) slonocomp:wrapper oleg$ python3.7

  &gt;&gt;&gt; import dotenv
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  ModuleNotFoundError: No module named 'dotenv'
  &gt;&gt;&gt;
  (env) slonocomp:wrapper oleg$
  </code></pre>
  
  <p>The question is Why? And how to avoid this error.</p>
