If you are using a mac and have Xcode installed on your machine, you can clone the repo and do the installation manually. Feel free to skip the installation steps if you have these tools available.
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew tap vapor/homebrew-tapbrew updatebrew install vapor
git clone email@example.com:LiveUI/Boost.git
or if you'd like to see what is going on ...
vapor xcode --verbose
You might also want to check schemes arguments and environmental variables to configure connection to your PostgreSQL database and other parameters needed to run Boost.
To configure your environmental variables edit Run scheme and see pre-set settings
