Got "Cannot read property 'width' of undefined"

[dnbard]

This function 71 line: gm(filepath).size(function(err, size) { } returns size that equals undefined. I've installed ImageMagick and all needed libs. (convert -help are working)

Grunt config:

image_resize: {
            '16px':{
                options: {
                    width: 16,
                    height: 16,
                    overwrite: true
                },
                files: [{
                    expand: true,
                    src: ['input/*.png'],
                    dest: 'out/'
                }]
            }
    }

And in fact some files are processed(until task find an error)

OS: Windows7

Upd: It's definitely not a wrong path issue.

I'm having the same issue. I'm also on Windows 7, ImageMagick is installed correctly.

+1, on OS X

In my case, on OS X, an older version of imagemagick was installed. I don't know about windows, but if it works partially I'd expect it to be the same problem.

Reinstalling did the trick on OS X (don't forget to update brew if you didn't before):

$ brew unlink imagemagick
