title: Creating conda env using packages from pip - PackageNotFoundError: Packages missing in current channels
body: <p>I'm trying to create a conda environment with a couple of packages that I have installed but it throws:
  <code>PackageNotFoundError: Packages missing in current channels</code></p>
  
  <p>important note: the packages that come back with above error are the ones that are installed using <code>pip</code>. so the question can be put as:</p>
  
  <p><strong>How to create a conda environment composed of packages that are installed using <code>pip</code>?</strong></p>
  
  <p>To be clear, packages are installed using conda pip at <code>~/anaconda3/bin/pip</code></p>
  
  <p><code>conda create --name myenvname scipy parquet</code></p>
