Module Not Found Error After Installing

[dano1066]

I used "npm install css-purge -g" from the main docs to install and when I run the following command "css-purge -i localcss.txt -o localcssnew.css"

internal/modules/cjs/loader.js:905
  throw err;
  ^

Error: Cannot find module 'C:\Users\dan\Desktop\blg\css-purge'

Tried to install the project by checking out the git repo and running npm install. This also throws exceptions.
