Matplotlib install failure on Mac OSX 10.8 Mountain Lion

Question

I tried to install matplotlib on my MacBook Air, but it always gives me this error message:

 Processing matplotlib-1.1.1_notests.tar.gz
 Running matplotlib-1         


        

Answer 1

I also use mac air with OS X ver 10.8.2.

Using following commands can get rid of this failure:
brew install freetype
brew install libpng
pip install matplotlib

That's all. There may be some warning in the installing process, but that does not affect.

Use following python code to test:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])
plt.ylabel('some numbers')
plt.show()  

which is referred from the url: http://matplotlib.org/users/pyplot_tutorial.html.
