title: Installing miniconda on alpine linux fails
body: <p>I have been attempting to install <code>miniconda</code> on an Alpine linux docker image. The minimal "working" example of my failure can be reproduced with Docker as follows:</p>
  
  <pre><code>docker run --rm -it alpine sh
  / # apk update &amp;&amp; apk add ca-certificates wget &amp;&amp; update-ca-certificates
  / # wget https://repo.continuum.io/miniconda/Miniconda3-4.3.27-Linux-x86_64.sh -O ~/miniconda.sh
  / # sh miniconda.sh -b 
  PREFIX=/root/miniconda3
  installing: python-3.6.2-h02fb82a_12 ...
  /root/miniconda.sh: line 361: /root/miniconda3/pkgs/python-3.6.2-h02fb82a_12/bin/python: not found
  </code></pre>
  
  <p>The file that it looks for is there, though:</p>
  
  <pre><code>/ # ls /root/miniconda3/pkgs/python-3.6.2-h02fb82a_12/bin/python
  /root/miniconda3/pkgs/python-3.6.2-h02fb82a_12/bin/python
  </code></pre>
  
  <p>I would appreciate some insight on this error. I have little idea of what to try next</p>
