Installation problem or error problem?

[mgifford]

I tried first to just run this on 1 URL:

% ./run.sh https://www.gsa.gov/real-estate
Error: 3 urls are needed as parameters
Parameters received:  [ 'https://www.gsa.gov/real-estate' ]
Audit of gsa.gov failed, exit code: 1

I was surprised that didn't work. Tried it again (on my Mac) with 4:

% ./run.sh https://www.gsa.gov/real-estate https://www.gsa.gov/travel-resources  https://www.gsa.gov/small-business https://www.gsa.gov/buying-selling/forecast-of-contracting-opportunities
Error: 3 urls are needed as parameters
Parameters received:  [
  'https://www.gsa.gov/real-estate',
  'https://www.gsa.gov/travel-resources',
  'https://www.gsa.gov/small-business',
  'https://www.gsa.gov/buying-selling/forecast-of-contracting-opportunities'
]
Audit of gsa.gov failed, exit code: 1

Not sure why it failed or what I'm missing.

is a certain version of Node or npm needed? If so might be useful to add to the Readme.
