To get Doubtfire installed on macOS, follow the steps below:

Once you have all of these steps complete you should be setup and ready to using Doubtfire.

Step 1: Installing doubtfire-api

1. Install Homebrew and Homebrew Cask

Install Homebrew for easy package management, if you haven't already, as well as Homebrew Cask:

$ /usr/bin/ruby -e "$(curl -fsSL"

$ brew tap caskroom/cask

2. Install rbenv and ruby-build

Install rbenv and ruby-build:

$ brew install ruby ruby-build rbenv

Add the following to your .bashrc:

$ echo 'eval "$(rbenv init -)"' >> ~/.bashrc

or, if you're using Oh-My-Zsh, add to your .zshrc:

$ echo 'eval "$(rbenv init -)"' >> ~/.zshrc

Now install Ruby v2.3.8:

$ rbenv install 2.3.8

Clone project and change your working directory to the api:

$ git clone

$ cd ./doubtfire-api

For switching the Ruby version to 2.3.8 use the following command:

$ rbenv local 2.3.8

3. Install Postgres

Install the Postgres App:

$ brew cask install postgres --appdir=/Applications

Ensure pg_config is on the PATH, and then login to Postgres:

$ export PATH=/Applications/*/bin:$PATH

$ psql

Create the Doubfire user the following at the Postgres prompt:


4. Install native tools

Install imagemagick at version 6, libmagic and ghostscript using Homebrew:

$ brew install imagemagick@6 libmagic ghostscript ffmpeg

$ brew link --force imagemagick@6

You will also need to install the Python pygments package:

$ sudo easy_install Pygments

If you are a developer for the project, it is usually better to create a fork for the repository and then follow the steps given below.

5. Install Doubtfire API dependencies

Set up overcommit and install hooks:

$ gem install overcommit -v 0.47.0

$ rbenv rehash

$ overcommit --install

Then install Doubtfire API dependencies using bundler:

$ gem install bundler -v 1.17.3

$ bundle install --without production replica staging

$ rbenv rehash

6. Create and populate Doubtfire

Whilst still in the Doubtfire API project root, execute:

$ bundle exec rake db:create

You can choose to populate the database with some fake test data using:

$ bundle exec rake db:populate

7. Install LaTex to generate PDFs

Install LaTeX now

$ brew cask install mactex

Follow the Generating PDFs guide to assist with installing LaTeX to generate PDFs. This step is optional unless you wish to generate PDF submissions.

8. Get it up and running!

Once you've installed using either the install script or the manual install steps, use the following command to run the api

$ bundle exec rails s

Step 2: Installing doubtfire-web

Continue below steps to manually install doubtfire-web on Mac OS. For installing Doubtfire-web dependencies we have to clone project and change working directory to web

$ git clone

$ cd ./doubtfire-web

Install Node.js either by downloading it and installing it manually, or via Homebrew on OS X:

$ brew install node

For switching the Ruby version to 2.3.8 use the following command:

$ rbenv local 2.3.8

Install overcommit and Ruby SASS:

$ gem install overcommit sass

If gem fails, you should read the Doubfire API README to install ruby. If you are not using rbenv, e.g., using Docker instead, you may need to prepend sudo to the above commands to have root write access.

If using rbenv, rehash to ensure each of the gems are on your PATH:

$ rbenv rehash

Install and sign the git hooks using overcommit:

$ overcommit --install
$ overcommit --sign

Install all node dependencies using npm, as well as grunt-cli globally:

$ npm install

Lastly, to compile and run a watch server and web server, use npm start:

$ npm start

This will automatically run the angular 1 grunt watch, and the angular 9 ng serve.

You can then navigate to the Doubtfire web interface at http://localhost:8000 on your web browser.

Step 3: Installing

Clone the project and change the working directory into it via,

$ git clone

$ cd ./

Then, follow the instructions in the "Getting Started" section of its file to setup the project and its development environment, locally.
