Error: Cannot find module './args'

I had a project on my old mac that uses npm and node. When I replaced the computer, I copied the file into the new mac, and run npm install and then tried to run a script with browserify that will transpile the code for ES6. I keep getting the error

Error: Cannot find module './args'

which I assume is not a module. I've also tried to reinstall the major modules individually but the error continues. Question: What does it mean when it says "cannot find module './args' and how do I fix that error?

 "scripts": {
    "build-js": "browserify app/app.js app/goopy.js app/models.js app/goofy.js -t babelify > app/bundle.js"
  },

package.json
