My node module is no longer working after updating to Maverick

Before installing Maverick my app worked well. After installing Maverick when i typed nodemon app.js in terminal it no longer worked so I reinstalled node and then npm uninstall nodemon followed by npm install nodemonto reinstall it. This worked well, and nodemon now works. Unfortunately now I have a new bug that I can't resolve. When uploading images in my app I get

TypeError: Cannot read property 'width' of undefined

        var gm = require('gm').subClass({ imageMagick: true }); 
        gm(target_path).size(function (err, size) {//shrinks and replaces large images
          if (size.width > 700 || size.height > 700) {  
            gm(target_path).scale(700, 700).autoOrient().write(target_path, function (err) {
              if (!err) console.log('shrunk! ');
            });
          }
        });

If I comment it out, and then just load up a page with an image I then get

Error: spawn ENOENT
    at errnoException (child_process.js:1001:11)
    at Process.ChildProcess._handle.onexit (child_process.js:792:34)
2 Oct 17:30:21 - [nodemon] app crashed - waiting for file changes before starting...

I have uninstalled and resinstalled fs, gm, imagemagick, jquery, and just about all my modules with no success. I have the following within usr/local/lib/node_modules and within my node_modules directory inside my project minus node and npm.

 $ ls
    bcrypt-nodejs   consolidate express     fs      gm      imagemagick jquery      mongodb     node-fs     nodemon     npm

Still getting this:
