I installed node js and npm via apt-get install and all of the dependencies, then I installed browserify
npm install browserify -g

You have to call "nodejs" and not "node". To verify this, type node -v on the shell: if nothing is found try nodejs -v. If that displays a version number, then the command you should be using is nodejs and not node. Therefore, you have to change the call to browserify in your script from node to nodejs (as shown below): replace
#!/usr/bin/env node
with
#!/usr/bin/env nodejs
You might also have to open the script as the superuser.
