With Homebrew on OSX

Homebrew is a package manager for Mac OS X (macOS). It can be installed in OSX with a single Ruby command:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Note

Homebrew requires XCode and the command line tools to be installed.

Installing MORSE

  1. Download Blender and copy the apps to /Applications. Blender is not currently available as a recipe in Homebrew.

    Note

    MORSE_BLENDER should be added to your .bashrc file and must point to the actual executable, not to the app directory, e.g.:

    MORSE_BLENDER=/Applications/Blender.app/Contents/MacOS/blender

  2. Check which version of Python is used by Blender. This can be done in a console,

    echo 'import sys; print("VERSION %s" % sys.version.split()[0]); sys.exit(0)' > /tmp/version.py
${MORSE_BLENDER} -y -P /tmp/version.py 2>&1 | grep VERSION

  3. Once you get the version used by Blender, grab the exact same version from the python website <http://www.python.org> and install it.

  4. Install MORSE using Homebrew:

    brew tap morse-simulator/morse
brew install morse-simulator

Note

If you have multiples version of Python 3 installed in /usr/local/bin, please specify the right one with --with-python=/usr/local/bin/python3.x.y.

Formula Options

The default the Homebrew formula configures and installs MORSE with support for only the sockets middleware. The following formula options are available to enable support for other middlewares:
