#!/usr/bin/env bash

set -e
cd $(dirname $0)

handle_requirements_file() {
  echo -e "\n\033[0;36m == Found requirements.txt at $1. Installing. == \033[0m\n"
  pip3 install -r $1
}
export -f handle_requirements_file

find . -name "requirements.txt" -type f -exec bash -c 'handle_requirements_file "$0"' {} \;
