Editing an atomosphere package, not seeing changes

Hi, I’m new to this side of Meteor. I’ve added an atmosphere package (https://atmospherejs.com/?q=pdfmake). I can get the package to work correctly. I am trying to modify the package slightly (editing file: myprojectdir/node_modules/pdfmake/build/pdfmake.js) and whenever I add console.log statements I don’t see my log statements within my meteor terminal. I have removed the ‘^0.1.25’ to just ‘0.1.25’ in my package.json file. I’ve stopped and started my meteor server, but still don’t see my log statements. What am I missing?
