![]() ![]() Please note that python3.rb was renamed to python.rb at some point. ![]() There is also: where you can install using brew install sashkab/python/python34 and brew link python34 -force Now you can use brew install with the corresponding commit hash: if you want to install a specific version then, you must check before install. This is another package manager but based and mainly meant for python, it also gives the equivalent of python's virtual environments and pyenv (as per other answer) and so each project can be in a different python and different libraries (Macports only switches python version for all projects) The issue with Homebrew is that it assumes that things in /usr/local are installed by it and so brew doctor will report these pythons and libraries as issues and as this question shows also the frameworks in /Library will be problematic.ĮDIT 8/2018 *** I would now suggest using conda either miniconda or anaconda. The other way is install direct from This will install a python into /usr/local/bin I think this installs a python and python3 executable. Install the 64bit version of Python 3, for instance from Install Python 3 using homebrew (brew install python) or by manually installing the package from Install python3 and python3-pip using the package manager of the Linux Distribution. e,g, to select macports python 2.7 port select -set python python27Įach package manager needs to run as the only package manager otherwise it will be confused with unexpected different versions of libraries and executables on its paths.įrom comments the similar homebrew way is given in Short answer seems to be brew switch the equivalent to port_select Python version managers For example to install 3.4 do sudo port install python34 There is also a python_select port that running it allows you to choose which version of python is run by /opt/bin/python. There are separate ports for several python versions 2.x and 3.x currently 2.4, 2.5, 2.6, 2.7 and 3.1, 3.2, 3.3 3.4 and 3.5. You can also download the full version of Xcode from the Mac App Store, or the minimal but unofficial OSX-GCC-Installer package. The fastest way is to install the Xcode Command Line Tools by running xcode-select -install. The first is using Macports as the package manager. Before installing Python, you’ll need to install a C compiler. Browse to the courselib folder (added above) in the Browse for Folder pop-up window ( /Users/ yourname/documents/workspace/courselib).I have done this sort of thing in two ways - however both do not coexist with homebrew although I suspect there should be a way similar to the macports one.Click the New Folder button (topmost, right of the bottom pane).Click the Libraries tab (leftmost, above the bottom pane).Disclose Interpreters by clicking the triangle in front of Interpreters or double-clicking Interpreters (after the triangle).Disclose PyDev by clicking the triangle in front of PyDev or double-clicking PyDev (after the triangle).Inform Eclipse to use the courselib folder in all Python projects.From time to time you will be asked to put other course-specific Python module files into this courselib folder these modules will be usable in all Python projects in Eclipse. The easiest way to do that is to install one of the binary installers for OS X from the Python Download page. Locate the workspace folder created in step 3 (see /Users/ yourname/Documents/workspace) and copy the courselib.zip file into this workspace and unzip it there, producing the courselib folder it should should contain a bunch of Python module files (ending in.Ensure the Save File radio button is depressed and click OK.
