Running brew doctor shows I have 3 different python "config" scripts installed. How do I get rid of them so that I no longer receive this warning? I have been told that there is a default Python installed on OSX, and that deleting it will cause SEVERE system issues, however, I want to clear these warnings in brew doctor.

This is what the message says:

    Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:
    /Library/Frameworks/Python.framework/Versions/2.7/bin/python-config
    /Library/Frameworks/Python.framework/Versions/2.7/bin/python2-config
    /Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7-config

Warning: Python is installed at /Library/Frameworks/Python.framework

Homebrew only supports building against the System-provided Python or a
brewed Python. In particular, Pythons installed to /Library can interfere
with other software installs.


How do I clear them and what happens if I just delete all three of those config scripts?
Those scripts refer to an official Apple installation of Python. You can uninstall those safely this way:


Open "Applications" in Mac Finder and drag Python to the trash bin.
Empty the trash bin


Note: 


the MacOS system Python is /usr/bin/python
Homebrew Python(s) will be located in /usr/local/bin/
Pythons installed as an Apple application live in /Library/Frameworks/Python.framework/
