TypeError: Cannot read property 'svg' of undefined

[cocap10]

Hi,

I couldn't get this script working.

What I did:

cd to_the_directory_which_contains_svgs
mkdir resized
/js/svg-resizer/svg-resizer.js -f -x 70 -y 70 -o resized/ *.svg 

What I got:

events.js:160
      throw er; // Unhandled 'error' event
      ^

Any idea about what is wrong ?
