Create empty conda environment : <p>I can create a new conda environment, with program <code>biopython</code> with this:</p>

<pre><code>conda create --name snowflakes biopython
</code></pre>

<p>What if I do not want to install any program? It seems I can not do that:</p>

<pre><code>» conda create --name tryout
Error: too few arguments, must supply command line package specs or --file

You can specify one or more default packages to install when creating
an environment.  Doing so allows you to call conda create without
explicitly providing any package names.

To set the provided packages, call conda config like this:

    conda config --add create_default_packages PACKAGE_NAME
</code></pre>
