I am using a Mac,

I try to use the ggplot as follow 

import matplotlib.pyplot as plt
plt.style.use('ggplot')

but I am always getting an error like 

File "/Users/Desktop/code.py", line 4, in <module>
    plt.style.use('ggplot')
AttributeError: 'module' object has no attribute 'style'

I have been checking to find a solution but I don't know where i am making a mistake. Any comment ?

As mentioned blow, I must upgrade the matplotlibhowever, I am getting error My python version is 2.7 so I tried this 

pip2 install matplotlib

and here are the errors

pip2 install -U matplotlib

It gives me a lot of error just few lines at the bottom blew

One way is to do 

sudo pip2 install -U matplotlib --ignore-installed six

You must use --ignore-installed six because of the fact that OS ships with six 1.4.1 installed and if one tries to uninstall it (because awscli depends on botocore, botocore depends on python-dateutil, and python-dateutil depends on six >= 1.5) it doesn't have permission to do so because System Integrity Protection doesn't allow even root to modify those directories.

This is highlighted here https://github.com/pypa/pip/issues/3165

After you do this, you can check the version of your matplotlibas 

python -c 'import matplotlib; print matplotlib.__version__'

If you get the error you mentioned as 

/usr/local/lib/python2.7/dist-packages/matplotlib/font_manager.py:273: UserWarning: Matplotlib is building the font cache using fc-list. This may take a moment.
  warnings.warn('Matplotlib is building the font cache using fc-list. This may take a moment.')

, then it is easy to solve it

open terminal

Then write python

Then 

>>> import matplotlib as mpl
>>> mpl.get_configdir()

Once you know the path, go to the finder -----> Go There search for the folder and remove fontList

Then run your program again, you will get the warning once more and it is solved. Further info, can be found here too for the second part matplotlib taking time when being imported
