title: Why conda cannot create environment with python=3.4 installed in it
body: <p>I have miniconda 3 installation and want to create conda environment with Python 3.4. I used the command: <code>conda create -n myenv python=3.4</code> and get the error: </p>
  
  <pre><code>PackagesNotFoundError: The following packages are not available from current channels:
    - python=3.4
  </code></pre>
  
  <p>I tried to change the version to 3.7, typing <code>conda create -n myenv python=3.7</code> 
  There was no error with version 3.7. So the problem seems to be related with the older versions of python. </p>
  
  <p>This is the full output with the error message:</p>
