Error while resizing image using imagemagick in nodejs , How to Fix this?

I am using imagemagick library for resizing image to fit for the UI specification,

I have installed imagemagick by following cmd: sudo npm install imagemagick

Installation is done correctly, but i am getting the error while resizing,

My code :

                var im = require('imagemagick');
                im.resize({
                            srcPath:"/tmp/"+imageName,
                            dstPath:"/home/image/" + imageName,
                            width:43,
                            height :43,
                       }, function(err, stdout, stderr){
                       if (err) {
                                console.log('error while resizing image ' + err);
                                }
                          });

I am getting the following error:

      Error: Command failed: execvp(): No such file or directory
