Mac Installation Instructions

As of version 0.3.1, an URBANopt installer (Mac OSX >= 10.12) is available to install the URBANopt CLI, Ruby 2.5.x, and OpenStudio SDK at the same time. If you’d rather install the dependencies manually, view the manual install section below.

For CLI usage examples, see our usage examples page

Install with the URBANopt Installer

  1. Download the desired version of the .dmg package.

  2. Use the GUI installer and choose a directory to install. Once installed, open a terminal and run the provided setup script. The generates env variables and stores them in a file in your home directory:

     . ~/
  3. When launching new shell terminals, run . ~/.env_uo.s to setup the environment.

Manual Install

  1. Install Ruby 2.5 (anything in the 2.5.x range will work). We recommend using rbenv to manage and install Ruby 2.5
    • brew install rbenv
    • rbenv install 2.5.x
    • Do not forget the rbenv init step of rbenv installation
    • Once installed, you may check which versions of Ruby have been installed and which one is active with: rbenv versions
    • Set your current directory to use Ruby 2.5.x with: rbenv local 2.5.x
    • Full documentation for rbenv can be found at the rbenv github site
  2. Install Bundler version 2.1:

     gem install bundler -v 2.1
  3. Install OpenStudio 3.0.1

  4. Add the RUBYLIB path as an “environment variable”, pointing to the OpenStudio Ruby location you just installed. You can use a text editor such as TextEdit, Sublime Text, vi or nano to open .bash_profile (or .zshenv if using zsh, the default since MacOS 10.15 Catalina). The following is an example using nano:

    1. Type the following in the terminal: nano ~/.bash_profile (or nano ~/.zshenv)
    2. Copy and paste export RUBYLIB=/Applications/OpenStudio-X.X.X/Ruby (where X.X.X is the OpenStudio version installed) at the top of the file
    3. Press control-x to exit, then y to save the changes, and the return key to go back to the terminal
  5. Install the URBANopt Command Line Interface (CLI):

     gem install urbanopt-cli

URBANopt CLI Usage

  1. View available CLI commands with:

     uo --help
  2. For detailed instructions, see the usage examples page.

OpenDSS and DiTTo Reader Set-up

As of version 0.4.0, the URBANopt CLI includes DiTTo/OpenDSS support. Since this functionality is implemented in Python, a different set of dependencies must be installed in order to use it.

If you’d like to use this functionality, follow the OpenDSS installation instructions.
