title: Why can't I install kivy-garden/garden.matplotlib using pip?
body: <p>I run a <code>pyenv</code> to use python 3.5.2 and <code>venv</code> to manage my packages. I can successfully install the <code>graph</code> flower from github, but not the <code>garden.matplotlib</code> flower.</p>
  
  <p>This command works fine:</p>
  
  <pre><code> .venv/bin/python3 -m pip install https://github.com/kivy-garden/graph/archive/master.zip
  </code></pre>
  
  <p>while this one downloads, but fails installation:</p>
  
  <pre><code>.venv/bin/python3 -m pip install https://github.com/kivy-garden/garden.matplotlib/archive/master.zip
  </code></pre>
  
  <p>How can I solve this? I need to develop the code on my Mac and run it on a raspberry pi afterwards.</p>
  
  <p>pip 19.2.2 (for this environment)</p>
