#             development environment
#          "travis" will install npm packages for components used in travis tests
#          "deployment" will install npm packages for components used in
#             deployment tests
#  base_directory: path of the base directory where we need npm packages to be installed
#  production  : array containing npm packages installation paths for
#                production components
#  test        : array containing npm packages installation paths for
