I am trying to install Python v.3.x in parallel with the already installed Python v.2.7.10. I'm following the procedure explained in this tutorial which I found on YouTube. Despite it seems not an hard procedure, in my case, when I launch the
brew doctor command, it returns:
MacBook-Pro-di-Rodolfo:~ Rodolfo$ brew doctor Please note that these warnings are just used to help the Homebrew maintainers with debugging if you file an issue. If everything you use Homebrew for is working fine: please don't worry and just ignore them. Thanks! 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. Warning: Unbrewed header files were found in /usr/local/include. If you didn't put them there on purpose they could cause problems when building Homebrew formulae, and may need to be deleted. Unexpected header files: /usr/local/include/jack/control.h /usr/local/include/jack/intclient.h /usr/local/include/jack/jack.h /usr/local/include/jack/jslist.h /usr/local/include/jack/metadata.h /usr/local/include/jack/midiport.h /usr/local/include/jack/net.h /usr/local/include/jack/ringbuffer.h /usr/local/include/jack/session.h /usr/local/include/jack/statistics.h /usr/local/include/jack/systemdeps.h /usr/local/include/jack/thread.h /usr/local/include/jack/transport.h /usr/local/include/jack/types.h /usr/local/include/jack/uuid.h /usr/local/include/jack/weakjack.h /usr/local/include/jack/weakmacros.h Warning: Unbrewed .pc files were found in /usr/local/lib/pkgconfig. If you didn't put them there on purpose they could cause problems when building Homebrew formulae, and may need to be deleted. Unexpected .pc files: /usr/local/lib/pkgconfig/jack.pc
These warnings refer to two packages that I installed before Homebrew which are Python v.2.7.10, plus relative applications, and JACK, an API for audio routing between applications. Their installation has been made through two ordinary .pkg downloaded files. So, in order to avoid possible future incompatibilities, how could I solve the warnings above reported? Are there alternative solutions to a brief uninstalling and reinstalling procedure? If it could be useful, I am using all these applications on OS X 10.9 Mavericks.
