I had the same problem and  in my case  the problem was that python was looking for packages in some ordered locations  first of all the default computer one where default old packages are   To check what your python is looking for you can do    gt  gt  gt  import sys  gt  gt  gt  print   n  join sys path    This was outputting the directory   System Library Frameworks Python framework Versions 2 7 Extras lib python  before pip or brew or port folders   The simple solution is   export PYTHONPATH   Library Python 2 7 site-packages  PYTHONPATH    This worked well for me  I advise you to add this line to your home bash profile file for the next time  Remember that sys path is built using the current working directory  followed by the directories in the PYTHONPATH environment variable  Then there are the installation-dependent default dirs

If you are using a version of enthought python  EPD  you might want to go directly to your site-packages and reinstall numpy  Then try to install pandas with pip  You will have to modify your installation prefix for that    If the problem persists  as it did with me  try downloading pandas tar ball  unpack it in your site packages and run setup py install from your pandas directory   If you got your dependencies right you can import pandas and check it imports smoothly

he easiest way to install Pandas  like almost every other package for Python  is with pip   Many packages  including Pandas  require a compiler  and a bunch of third-party DLLs  and many Windows users don t know how to deal with that  That s exactly why the  wheel  format was created  so packages can upload pre-built binaries   Not every project has pre-built binary wheels for Windows yet  But you can look at Christoph Gohlke s site and find wheels for all of the most popular ones  Just follow the instructions on that page to download the wheel file and install it with pip   But in the case of Pandas  you don t have to do that  They have wheels on their download page  and uploaded to PyPI  And the documentation tells you to use these   Well  it first suggests you use Anaconda Miniconda  but if you want a stock Python  use pip and the packages on PyPI   it worked for me    on windows 7 64 bit  python 3 4

This worked for me under 10 7 5 with EPD free-7 3-2 from Enthought   Install EPD free  then follow the step in the following link to create  bash profile file    http   redfinsolutions com blog creating-bashprofile-your-mac  And add the following to the file    PATH   Library Frameworks Python framework Versions Current bin   PATH    export PATH   Execute the following command in Terminal    sudo easy install pandas   When finished  launch PyLab and type   In  1   import pandas  In  2   plot arange 10     This should open a plot with a diagonal straight line

If you re like me and you don t like the idea of deleting things that were part of the standard system installation  which others have suggested  then you might like the solution I ended up using    Get Homebrew - it s a one-line shell script to install  Edit your  profile  or whatever is appropriate  and put  usr local bin at the start of your PATH so that Homebrew binaries are found before system binaries brew install python - this installs a newer version of python in  usr local pip install pandas   This worked for me in OS X 10 8 2  and I can t see any reason it shouldn t work in 10 6 8

I had this exact problem    The issue is that there is an old version of numpy in the default mac install  and that pip install pandas sees that one first and fails -- not going on to see that there is a newer version that pip herself has installed     If you re on a default mac install  and you ve done pip install numpy --upgrade to be sure you re up to date  but pip install pandas still fails due to an old numpy  try the following      cd  System Library Frameworks Python framework Versions 2 7 Extras lib python    sudo rm -r numpy   pip install pandas   This should now install   build pandas   To check it out what we ve done  do the following  start python  and import numpy and import pandas  With any luck  numpy   version   will be 1 6 2  or greater   and pandas   version   will be 0 9 1  or greater      If you d like to see where pip has put  found   them  just print numpy  and print pandas

Don t know if you solved the problem but if anyone has this problem in future    python  gt  gt import numpy  gt  gt print numpy    Go to the location printed and delete the numpy installation found there  You can then use pip or easy install

You probably have another Numpy version installed on your system   try to query your numpy version and retrieve it if your distribution does not support it  aka debian unbuntu Mint version can query mostly from dpkg package manger   dpkg --get-selections   egrep -i  numpy   you can see actual Numpy version    Some having apt can either asking to removing it by doing this  apt-get remove numpy  Some having distribution like Fedora  RedHat and any compatible release under RedHat model can use rpm as well to query the installation   This is happening by telling to Numpy installer to install itself in current  usr local lib python VERSION  dist-packages over Linux env and c       python VERSION  site-packages for windows  Having probably One version of Numpy installed in  usr local python VERSION  dist-packages  this one will be instantiated first    pth file hold information about path location of specific python module  but erasing a component from packages may corrupt it       Be careful  and you will have to remove the package and all it s dependency    really painful in some case    Visiting lunchad net may save you time sometimes they had new versions from some packages

I work with the guys that created Anaconda Python   You can install multiple versions of python and numpy without corrupting your system python    It s free and open source  OSX  linux  Windows    The paid packages are enhancements on top of the free version   Pandas is included   conda create --name np17py27 anaconda 1 4 numpy 1 7 python 2 7 export PATH   anaconda envs np17py27 bin  PATH   If you want numpy 1 6   conda create --name np16py27 anaconda 1 4 numpy 1 6 python 2 7   Setting your PATH sets up where to find python and ipython   The environments  np17py27  can be named whatever you would like
