I'm trying to install to the fresh VM with Ubuntu Server 16.04. Commands are as follows:
sudo apt-get install ruby ruby-dev -y
sudo apt-get install nodejs -y
# git is already installed, but I'm following prescriptions
sudo apt-get install git -y
sudo apt-get install libsqlite3-dev build-essential patch zlib1g-dev liblzma-dev -y
# cannot install without sudo - don't have write permissions for the /var/lib/gems/2.3.0 directory
sudo gem install rails
sudo gem install bundler
git clone https://github.com/dphuang2/PoGoBag.git
cd PoGoBag/
bundle install --without production

Installing google-protobuf 3.0.0

rake db:setup
rails s -b 0.0.0.0

I don't know absolutely no RoR, but I think protobuf is installed:
$ bundle show protobuf
/var/lib/gems/2.3.0/gems/google-protobuf-3.0.0-x86_64-linux
$ bundle show google/protobuf
Could not find gem 'google/protobuf'.
