Mac OSX equal to linux time command

$PATH should contain these folders: /usr/bin:/usr/sbin:/bin:/sbin.

Try editing ~/.bash_profile, ~/.profile, or ~/.bash_login (with for example /usr/bin/open ~/.bash_profile -a TextEdit) and commenting out any lines that modify the path.

If that works, you can add a line like export PATH=/opt/local/bin:/opt/local/sbin:$PATH to ~/.bash_profile.

The fix I ended up was removing all home brew Python and fixing up the system Python.

brew remove python
brew remove python3
brew cleanup

Check for the system pip and python (or absence of pip is OK too).

which python
which pip
which pip3
which python3

At this point, you need to easy_install a system based pip:

sudo easy_install --upgrade pip
pip --version

You should now have a pip that's based on /Library/Python (and pip 7.1.2 against python 2.7 for El Capitan in October 2015)

mac:~ me$ pip --version
pip 7.1.2 from /Library/Python/2.7/site-packages/pip-7.1.2-py2.7.egg (python 2.7)
mac:~ me$ which pip
/usr/local/bin/pip
mac:~ me$ which python
/usr/bin/python
