"ValueError: unknown locale: UTF-8" when importing pandas in python 2.7 [duplicate]

I'm very new in python and would like to learn using pandas, but I can't even use the package properly in my python.

In the terminal I tried

$ conda install pandas 

The result is:

Fetching package metadata ....... Solving package specifications: ..........  # All requested packages already installed. # packages in environment at /Users/rudyyuan/anaconda: # pandas                    0.18.1              np111py27_0   Rudy-Yuans-MBP:~ rudyyuan$  

Then I tried to install using pip:

Rudy-Yuans-MBP:~ rudyyuan$ pip install pandas Requirement already satisfied (use --upgrade to upgrade): pandas in         ./anaconda/lib/python2.7/site-packages Requirement already satisfied (use --upgrade to upgrade): python-dateutil in      ./anaconda/lib/python2.7/site-packages (from pandas) Requirement already satisfied (use --upgrade to upgrade): pytz>=2011k in     ./anaconda/lib/python2.7/site-packages (from pandas) Requirement already satisfied (use --upgrade to upgrade): numpy>=1.7.0 in  ./anaconda/lib/python2.7/site-packages (from pandas) Requirement already satisfied (use --upgrade to upgrade): six>=1.5 in ./anaconda/lib/python2.7/site-packages (from python-dateutil->pandas) 

Then I enter

$ python 

Then I enter

$ import pandas 

The result of the commands entered:

But when I tried to check packages locally using this:

import pip sorted(["%s==%s" % (i.key, i.version) for i in pip.get_installed_distributions()]) 

it shown pandas already inside....:

Looks like you're on OS X. Append this to your ~/.bash_profile:

export LC_ALL=en_US.UTF-8 export LANG=en_US.UTF-8 

And then run:

$ source ~/.bash_profile 

Now try import pandas.
