Having experience with BSD and Gentoo, I am extremely familiar with Ports/Portage and like the system very much. You really should give one or both of MacPorts and fink a try.

MacPorts, fink, and a few other projects are attempts to provide that Linux-like functionality to us Mac owners.

One of the nice things about linux is that the huge array of high quality open source tools that can be downloaded for free from a trustworthy site. So, for example, you could add the following to ~/.I can't resist: What is wrong with MacPorts (or fink as an alternative)? If you don't want to bother learning, just do ~/.profile and then don't complain if it wasn't what you wanted.Įither way, you need to make sure that the appropriate path comes before /usr/bin in the PATH. (All users or just one user? bash or any shell? And so on.) If you don't know which one you want, you really should do some research. Which profile file is appropriate depends on what you want to affect. If you only care about command-line sessions (both Terminal.app and remote ssh), you can instead just do the standard Unix thing of editing the appropriate profile file.

It's also what the Homebrew FAQ and Python FAQ suggest. If you want to affect GUI apps (and LaunchAgents, etc.), there is apparently no longer a supported way to do this, but the deprecated QA1067 does seem to still work in Lion. Whatever the path is, you need to edit your PATH variable. /Library/Frameworks/amework/Versions/2.7/bin.Depending on which alternate Python you've installed and which instructions you followed, this could be: Second, make sure the path to the alternate Python's scripts and binaries comes before Apple's in the PATH. Otherwise, they'll both succeed, one will end up overwriting the other, and you will have no way of running the overwritten version.

For example, if you install ipython for both Apple 2.7 and Homebrew 2.7, both will attempt to create scripts named /usr/local/bin/ipython and /usr/local/bin/ipython-2.7. If you're using a non-Apple build of Python 2.7, and you want to avoid the PATH problems, you have to do two things:įirst, do not, ever, install any Python packages that include scripts or binaries (including pip itself) in more than one Python. If not, the instructions are basically the same as above, but you'll have to guess which steps to skip or follow, whether to sudo, etc. Third-party binary installs like Enthought and ActiveState may already include scipy and everything else you need. If you're using MacPorts, Fink, gentoo-alt, etc., you should install the scipy package that comes with your package manager, and it will drag in whatever else it needs (maybe even including rebuilding Python and GCC). Some third-party installs, like Homebrew or ActiveState, include pip.įor Python 3.3 or later, you may want to use the built-in venv instead of virtualenv.If your 3.4+ doesn't already have pip, you may want to python -m ensurepip to install it. Python 3.4 or later may (and will, if from a installer) include a pip bootstrap.If you're using virtualenv/ venv, your virtual environments will already include pip.But first make sure you don't already have it. (Besides the security and robustness benefits, this may save you a whole lot of time by making you compatible with binary wheels for some of the scientific stack or other modules.)įor most non-Apple Python installations (and maybe even Apple's in 10.9 or 10.10 I haven't checked), you should not use easy_install to install pip. If you already have pip, but fear it may be out of date, pip install -upgrade pip. will be for Apple's Python python3, pip3.3, etc. There will be no collisions, because python, pip2.7, etc. The exception to this is if you want a Python 3.x version, in which case installing it from or Homebrew is perfectly reasonable. Keeping the paths, installed packages, etc. If you're using a different version of Python, you really should consider not doing so. The instructions above are for Apple's pre-installed version(s) of Python.
