Node.js Question

Got issue with upload and resize image in express js

var express = require("express"),
app = express(),
formidable = require('formidable'),
util = require('util'),
fs = require('fs-extra'),
qt = require('quickthumb');

// Use quickthumb
app.use(qt.static(__dirname + '/'));

app.post('/upload', function (req, res){
var form = new formidable.IncomingForm();
form.parse(req, function(err, fields, files) {
res.writeHead(200, {'content-type': 'text/plain'});
res.write('received upload:\n\n');
res.end(util.inspect({fields: fields, files: files}));
});

form.on('end', function(fields, files) {
/* Temporary location of our uploaded file */
var temp_path = this.openedFiles[0].path;
/* The file name of the uploaded file */
var file_name = this.openedFiles[0].name;
/* Location where we want to copy the uploaded file */
var new_location = 'uploads/';

fs.copy(temp_path, new_location + file_name, function(err) {
if (err) {
console.error(err);
} else {
console.log("success!")
}
});
});
});

// Show the upload form
app.get('/', function (req, res){
res.writeHead(200, {'Content-Type': 'text/html' });
var form = '<form action="/upload" enctype="multipart/form-data" method="post">Add a title: <input name="title" type="text" /><br><br><input multiple="multiple" name="upload" type="file" /><br><br><input type="submit" value="Upload" /></form>';
res.end(form);
});
app.listen(8080);


I am a fresher on node js and express js. I followed this guy's blog to upload and resize image. The above is the code part. The upload function is working. However, in terms of resize function, if I want to resize uploaded image, I got this error:

events.js:85
throw er; // Unhandled 'error' event
^
Error: spawn identify ENOENT
at exports._errnoException (util.js:746:11)

Answer

Did you install imagemagick? Quickthumb requires it for work.
