phantomjs://code/yslow.js:5 in global code

[KennethNagin]

I'm new to yslow. I did the in windows install but getting an error when running your basic commands:
$ ./bin/phantomjs.exe yslow.js --info basic --format tap --threshold B http://yslow.org
TypeError: undefined is not an object (evaluating 'args.length')

phantomjs://code/yslow.js:5 in global code

I also did the linux install on ubuntu and got the same error message.
What am I missing

I've encountered the same issue.
at the start of line 5:
var i,arg,page,urlCount,viewport,webpage=require("webpage"),args=phantom.args,len=args.length
change "args=phantom.args,len=args.length"
to "args=phantom.args;var len=args.length"
