title: conda: package missing after installing offline
body: <p>I need to create a conda env with elasticsearch on a machine with no internet. I scp'd elasticsearch-5.3.0-py36_0.tar.bz2 to the machine and ran the following:</p>
  
  <pre><code>conda install elasticsearch-5.3.0-py36_0.tar.bz2

  $ conda list | grep elasticsearch
  elasticsearch             5.3.0                    py36_0    &lt;unknown&gt;
  </code></pre>
  
  <p>Then, I tried to create the env as follows:</p>
  
  <pre><code>conda create -n my_env --offline --copy -y -q  elasticsearch
  </code></pre>
  
  <p>However, this fails with: </p>
  
  <pre><code>Using Anaconda Cloud api site https://api.anaconda.org
  Fetching package metadata:

  Error:  Package missing in current linux-64 channels:
    - elasticsearch
  
  You can search for this package on anaconda.org with
  
      anaconda search -t conda elasticsearch
  </code></pre>
  
  <p>What do I need to do to create this env?</p>
