title: cannot import name 'ft2font' from 'matplotlib' on windows10
body: <p>I am using a windows10 machine and using PyCharm as my IDE, so when I tried to run the below code, it shows the following error</p>
  
  <p>I tried uninstalling and re-installing matplotlib and also as someone from SO suggested used --force reinstall too, but didn't work</p>
  
  <p>It was working well until yesterday</p>
  
  <pre><code>import matplotlib.pyplot as plt
  import numpy as np
  
   rng = np.random.RandomState(42)
   X = 10 * rng.rand(50)
   y = 2 * X - 1 + rng.randn(50)
  
  plt.scatter(X, y)
  plt.show()
