11,964 PointsProblem Installing Ruby and Python Environments, possibly due to GCC / Xcode incompatibility?
I am unable to install Python 3.4 or mySQL through homebrew. I keep getting messages about having GCC installed and how that causes packages to fail.
I get this error message when I try to install python:
Warning: You seem to have osx-gcc-installer installed.
Homebrew doesn't support osx-gcc-installer. It causes many builds to fail and
is an unlicensed distribution of really old Xcode files.
Please run xcode-select --install
to install the CLT.
Warning: You have an outdated version of /usr/bin/install_name_tool installed.
This will cause binary package installations to fail.
This can happen if you install osx-gcc-installer or RailsInstaller.
To restore it, you must reinstall OS X or restore the binary from
the OS packages.
I searched around on the internet and it looks like there are some major issues with GCC and Xcode. How can I go about reinstalling everything so that I can get all the stuff I need?

Treehouse Guest TeacherFirst off, do you have Xcode installed? If no, install it. Then run the xcode-select --install
command which, IIRC, install the command line tools for compiling packages (I hate that OS X doesn't come with GCC and friends pre-installed). Then you should be able to brew install
things.
