Mac version is the newest, and i installed pip, as the method pip install scan-build, I got an error.
Thanks to come back... So, you are not running the tool, but trying to install it? Have you check which Python version you have, as the error message suggested? Do you have virtualenv or virtualenvwrapper installed? (That might help to run different version of Python installed and used on the same machine.)
