I am getting this error on using matplotlib

Question

I get this error on typing this in python command prompt: import matplotlib.pyplot as plt

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    import matplotlib.pyplot as plt
  File "/Library/Python/2.7/site-packages/matplotlib-1.3.x-py2.7-macosx-10.8-intel.egg/matplotlib/pyplot.py", line 97, in <module>

  Referenced from: /Library/Python/2.7/site-packages/matplotlib-1.3.x-py2.7-macosx-10.8-intel.egg/matplotlib/backends/_macosx.so
  Reason: image not found

Can someone suggest me, how i can fix this ? I had installed all the packages with this shell script

https://github.com/fonnesbeck/ScipySuperpack

Is there anything that i am missing ? Any additional configuration ?

I am seconding andershqst for OSX 10.7.4:

Go to this directory:

cd /System/Library/Frameworks

Verify that this path exists:

ls /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/CoreText.framework/Versions/A/CoreText

Create this soft link:

sudo ln -s /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/CoreText.framework Coretext.framework

Then test your fix, as described in this tutorial.

This worked for me, but the path I had to verify existed was the same I then symlinked, not the one he mentions need to be verified. I.e. it was the suggested path with the .framework suffix: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/CoreText.framework.

I had the same problem using ScipySuperpack and solved it the following way.

Open terminal and locate the path to CoreText.framework file

sudo find / -name "CoreText.framework"

Create a symbolic link from the CoreText file at the located path, to the path in the ImportError

sudo ln -s path_located path_where_it_is_missing

At this point I got another build error because I run OSX 10.7.5 (10.8 being the one you'll currently get from the ScipySuperpack page) In that case, get the ScipySuperpack from here and answer 'yes' when prompted 'Are you installing from a repository cloned to this machine (if unsure, answer no)? (y/n)'
