If you have different projects developed in either Python 2 or 3 and each requiring specific libraries, you might consider using sandboxed Python environments. Isolated Python environments using virtualenv Now run which python3 to determine the path where Homebrew installed the progam file:Īt this stage we have two different version of Python available, yet both version are invoked differently : After installation, run the python3 -version command to verify the exact version: Great so we have access to Python 2.x, now lets add Python 3.xĪssuming you have Homebrew installed, in Terminal.app execute the following command to install Python 3 : brew install python3. usr/bin/python Install Python 3 with Homebrew If you execute which python via the command line, it will return the location of the program file, in this case: If you execute this command in macOS 10.13.x for example, the returned output will read: Open Terminal.app (~/Applications/Utilities) and type python -version running multiple Python verions as sandboxed environments.The following instructions will guide you through the process of: ![]() But what if you have a project which requires Python 3 ? I tried the opencamlib brew recipe - that failed to build and targets Python2.The latest version of macOS 10.13.3 has Python 2.7.10 installed by default, yet Python has been available on macOS and previously OS X for quite a while now.Ĭonsult the Apple's Open Source Reference Library, and browse through the various releases of the OS to find out which Python version was included). Mah$ /Applications/FreeCAD.app/Contents/MacOS/FreeCAD -M /usr/local/lib/python3.7/site-packages However, FreeCAD needs to be told about this site-packages directory like so: Type "help", "copyright", "credits" or "license" for more information. Installing: /usr/local/Cellar/python/3.7.3/Frameworks/amework/Versions/3.7/lib/python3.7/site-packages/ocl.soīrew softlinks the /usr/local/Cellar/python/3.7.3/Frameworks/amework/Versions/3.7/lib/python3.7 directory to /usr/local/lib/python3.7/site-packages, and the standalone Python3 interpreter properly finds the ocl module: $ CXXFLAGS=-isystem\ /usr/local/include cmake -DBUILD_PY_LIB=ON -DUSE_PY_3=ON. # this builds the C library and the Python3 ocl module: # for some reason, cmake does not properly pick up the boost include path $ git clone git:///aewallin/opencamlib.git To get opencamlib to build and work, jump the following hoops: ModuleNotFoundError: No module named 'ocl' © Juergen Riegel, Werner Mayer, Yorik van Havre 2001-2019 Mah$ /Applications/FreeCAD.app/Contents/MacOS/FreeCAD Since the long hangs described in are still there, I start FC from a terminal like so: I have Python3 installed via 'brew install python3' - the Apple-supplied Python interpreter is still 2.7.įreecad is straight off. However, when installing wxPython on a 3.8. Since not too many people seem to use FC on macOS - here are my notes on getting FC 01.9pre with Python3 and Opencamlib to work on macOS. Using pyenv and python 3.6.9 I am able to get my application to work on a MacOS 10.14.
