I am attempting to install the python package pandas . All my existing python

  • 0

I am attempting to install the python package pandas.

All my existing python gear has been installed using home-brew / easy_install / pip, however pip and easy_install both fail on pandas — claiming that i do not have numpy > 1.6 (though when in python numpy.__version__ returns 1.6.2).

Despite this pip install numpy --upgrade reports that I am up-to-date.

To hack around this, I git-cloned the source code down, and ran python setup.py install in my /Library/Python/... directory. It seemed to build okay, however when i import pandas, i get an error and i’m not sure what to do about it.

Can anyone help me link the compiled library to my existing install?

The error follows:

    This was discussed and resolved on GitHub: https://github.com/pydata/pandas/issues/2188. The issue had to due with Clang’s C99 behavior w.r.t. inline C functions.
