Cannot Install sklearn with pip on Mac

Question

I got the following error message when trying to install scikit-learn on a Mac: http://pastebin.com/sfsbqcm6

I tried to install scikit-learn using this command:

pip install scikit-learn

I found on other questions about the -arch ppc flag, but I'm not sure how to edit the argument with pip install scikit-learn command.

Answer 1

Later I realized that I'm using a 32 bit version of Python which wasn't compatible with scipy and gave errors. I followed instructions on how to uninstall python and install 64 bit, and now I could successfully install scipy, numpy, etc. So check your python version!
