I'm trying to install python3 using brew on a 2008 MacBook (OSX Lion).
I have a few years using apt-get in Linux environments, but this is my first time trying to install something using brew.
Per the instructions at Get Your Mac Ready For Python Programming and Install Python 3 on Mac OS X and use virtualenv and virtualenvwrapper I entered:
brew install python3
This was after accidentally trying to install version 2.x of python using
brew install python
The python package installs fine, but when trying to install python3 I get
gcc-6 -Wno-unused-result -Wsign-compare -fno-common -dynamic -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -o FileSettings.o -c ./FileSettings.m In file included from /System/Library/Frameworks/Foundation.framework/Headers/Foundation.h:120:0, from ./FileSettings.h:9, from ./FileSettings.m:9: /System/Library/Frameworks/Foundation.framework/Headers/NSTask.h:75:24: error: expected identifier or '(' before '^' token @property (copy) void (^terminationHandler)(NSTask *) NS_AVAILABLE(10_7, NA); ^ /System/Library/Frameworks/Foundation.framework/Headers/NSTask.h:78:1: error: expected identifier before 'end' @end ^ make: *** [FileSettings.o] Error 1 make: *** [install_PythonLauncher] Error 2 make: *** [frameworkinstallapps] Error 2 READ THIS: https://git.io/brew-troubleshooting If reporting this issue please do so at (not Homebrew/brew): https://github.com/Homebrew/homebrew-core/issues These open issues may also help: python & python3: fix sqlite3 on sierra https://github.com/Homebrew/homebrew-core/pull/3134 Warning: You are using OS X 10.7.
Per the errors I checked python & python3: fix sqlite3 on sierra which seems to indicate the fault lies somewhere with sqlite3 however the link at python3 (v 3.5.1) failed to build on 10.7.5-x86_64 indicates its an issue with the compiler?
I'm not sure where to go next in the troubleshooting process.
