title: Anaconda can't import installed package matplotlib-venn
body: <p>I'm about to give up on Anaconda. I never had trouble managing my packages with <code>pip</code> and I just thought I'd try it since now there's one package I can't get with <code>pip</code> and I'd heard so many good things about it.</p>
  
  <p>I can't import a package I just installed with Anaconda, similar to <a href="https://stackoverflow.com/questions/45386933/cant-import-a-package-installed-in-anaconda">this</a> but on MacOS instead of Windows.</p>
  
  <p>I really don't <em>want</em> multiple environments unless I have to have them. I want to be able to run most/all of my packages from the same scripts. I have a virtual environment named py37 where I've been putting most things. Among other packages:</p>
  
  <pre><code>(py37) jennifers-mbp:~ jenniferlongdiaz$ conda list
  #packages in environment at /anaconda3/envs/py37:
  #
  # Name                    Version                   Build  Channel    
  matplotlib-venn           0.11.5                     py_1    conda-forge
  numpy                     1.15.3           py37h6a91979_0  
  python                    3.7.1                haf84260_3  
  </code></pre>
  
  <p>Python goes to the right installation:</p>
  
  <pre><code>(py37) jennifers-mbp:~ jenniferlongdiaz$ which python
  /anaconda3/envs/py37/bin/python
  (py37) jennifers-mbp:~ jenniferlongdiaz$ python
  Python 3.7.1 (default, Oct 23 2018, 14:07:42) 
  [Clang 4.0.1 (tags/RELEASE_401/final)] :: Anaconda, Inc. on darwin
  Type "help", "copyright", "credits" or "license" for more information.
  </code></pre>
  
  <p>I can import numpy but not matplotlib-venn:</p>
  
  <pre><code>&gt;&gt;&gt; import numpy as np
  &gt;&gt;&gt; import matplotlib_venn as venn
  </code></pre>
  
  <p>...bunch of stuff and then:</p>
  
  <pre><code>ImportError: cannot import name 'get_backend' from 'matplotlib' (/anaconda3/envs/py37/lib/python3.7/site-packages/matplotlib/__init__.py)
  </code></pre>
  
  <p>Similiarly:</p>
  
  <pre><code>&gt;&gt;&gt; from matplotlib import get_backend
  </code></pre>
  
  <p>...bunch of stuff and then:</p>
  
  <pre><code>ImportError: cannot import name 'get_backend' from 'matplotlib' (/anaconda3/envs/py37/lib/python3.7/site-packages/matplotlib/__init__.py)
  </code></pre>
  
  <p>From within the IDE spyder (<code>(py37) jennifers-mbp:~ jenniferlongdiaz$ spyder</code>), I get:</p>
  
  <pre><code>In [1]: import matplotlib_venn as venn
  Traceback (most recent call last):
  
    File "&lt;ipython-input-9-aafbc15b97e7&gt;", line 1, in &lt;module&gt;
      import matplotlib_venn as venn
  
  ModuleNotFoundError: No module named 'matplotlib_venn'
  </code></pre>
  
  <p>Please help!</p>
