title: How can I install mpmath as an external library for Blender?
body: <p>I'm interested in trying out sympy with Blender (v2.76, Python 3.4.2 Console, Windows 8.1). I followed this <a href="https://blender.stackexchange.com/questions/15453/error-import-point3d-of-geometry-module-of-sympy0-7-5-in-blender2-71/15513#15513">answer</a> from Blender SE, downloaded sympy as a ZIP from Githib, and moved the sympy folder to C:\Program Files\Blender Foundation\Blender\2.76\python\lib\site-packages. However, when I opened Blender and tried to import sympy in the Python Console, I got the following error:</p>
  
  <pre><code>&gt;&gt;&gt; import sympy
  Traceback (most recent call last):
    File "&lt;blender_console&gt;", line 1, in &lt;module&gt;
    File "C:\Program Files\Blender Foundation\Blender\2.76\python\lib\site-packages\sympy\__init__.py", line 20, in &lt;module&gt;
      raise ImportError("SymPy now depends on mpmath as an external library. "
  ImportError: SymPy now depends on mpmath as an external library. See http://docs.sympy.org/latest/install.html#mpmath for more information. 
  </code></pre>
  
  <p>I don't know how to install an external library. I tried going to the <a href="http://docs.sympy.org/latest/install.html#mpmath" rel="nofollow noreferrer">link</a> mentioned in the ImportError, and I saw <code>pip install mpmath</code>. I tried it in cmd, but got this:</p>
  
  <pre><code>&gt;pip install mpmath
  Requirement already satisfied (use --upgrade to upgrade): mpmath in c:\anaconda3
  \lib\site-packages
  </code></pre>
  
  <p>I did install Anaconda a while ago, so I guess it makes sense to have this output. How can I install mpmath as an external library for Blender so I can import sympy in it?</p>
