Node js + imagemagick + Error: spawn ENOENT

问题

Hi am trying to implement Imagemagick package using node.js

I added my following code.

var im = require('imagemagick');

router.post('/conversation/start', function(req, res) {

    var args = ["/public/images/team/rajini.jpg", "-crop", "120x80+30+15", "output.png"];

    im.convert(args, function(err) {
        if (err) {
            throw err;
        }
        res.end("Image crop complete");
    });
});

But i getting the following error in terminal.

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: spawn ENOENT
    at errnoException (child_process.js:988:11)
