Hi I'm trying to install scikit-learn in Python on a mac, but failed. Does anyone having idea how to fix this? Thanks! The error message is as follows.

Error message

Command /usr/bin/python -c "import setuptools, tokenize;file='/private/tmp/pip_build_root/scikit-learn/setup.py';exec(compile(getattr(tokenize, 'open', open)(file).read().replace('\r\n', '\n'), file, 'exec'))" install --record /tmp/pip-UfI2WG-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /private/tmp/pip_build_root/scikit-learn

Storing debug log for failure in /Users/yuxinsun/Library/Logs/pip.log

pip.log is like this. (sorry i have to change a little for links in pip.log since i can't attach more than 2 links, but i think the links are not so crucial)

/usr/local/bin/pip run on Sun Mar 23 02:25:36 2014

I ran into this same error with pip install -U scikit-learn on Ubuntu 14.04. I believe it's an insufficient permissions issue on the file /private/tmp/pip_build_root/scikit-learn/setup.py. I resolved it by elevating permissions on pip with sudo pip install -U scikit-learn

I upgrade pip from 7.1.2 to 8.1 and it fixed the issue

It is best practise to set up an environment to do this. Anaconda (or Miniconda) handles the requirements/dependencies pretty well.
