python pandas and matplotlib installation conflict
Question: I am using a Mac OSX Yosemite 10.10.5 and I am trying to practice data science
with python on my laptop. I am using python 3.5.1 on a virtualenv however when
I install pandas and matplotlib seems like both of them are having a conflict
when trying to be imported. Both has same error and the output is:

    
    
    >>> import matplotlib
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/Users/deanarmada/.virtualenvs/python3-data-science/lib/python3.5/site-packages/matplotlib/__init__.py", line 1131, in <module>

        raise ValueError('unknown locale: %s' % localename)
    ValueError: unknown locale: UTF-8
    


Answer: Just run:

    
    
    export LC_ALL=C
    

before accessing python through terminal.
