Node js Error: spawn ENOENT

Question

I am trying to convert SVG to PNG with node js. My code is here:

http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'image/png'});
  var convert = child_proc.spawn("convert", ["svg:", "png:-"]),
      values = (url.parse(req.url, true).query['values'] || ".5,.5")
        .split(",")
        .map(function(v){return parseFloat(v)});

  convert.stdout.on('data', function (data) {
    res.write(data);
  });
  convert.on('exit', function(code) {
    res.end();
  });

  jsdom.env({features:{QuerySelector:true}, html:htmlStub, scripts:scripts, done:function(errors, window) {
    var svgsrc = window.insertPie("#pie", w, h, values).innerHTML;
    //jsdom's domToHTML will lowercase element names
    svgsrc = svgsrc.replace(/radialgradient/g,'radialGradient');
    convert.stdin.write(svgsrc);
    convert.stdin.end();
  }});
}).listen(8888);

While executing I got this error (in MAC)

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: spawn ENOENT
    at errnoException (child_process.js:980:11)
    at Process.ChildProcess._handle.onexit (child_process.js:771:34)

I have specified the path for nodejs. But i dont know why it fails. Any idea about this issue?

It's likely failing because it can't find the convert application. Does the path to convert exist in your environment PATH? Can you run convert from your terminal?

For others, see also [this issue](http://stackoverflow.com/questions/17516772/using-nodejss-spawn-causes-unknown-option-and-error-spawn-enoent-err). Simply replacing `spawn` by `exec` fixed all of my problems (linux binary in PATH with permissions wouldn't execute). – msanford Apr 08 '14 at 15:28
Is there a way to specify that dependency so that npm install tells the so to install the package? – krusty.ar Sep 10 '14 at 15:10

I was getting the error

Uncaught Error: spawn myExeCommand ENOENT

Once I added 'options' to the spawn(), it worked.

let options = {shell: true};
let theProcess = child_process.spawn(myExeCommand, null, options);

I had this same issue running from Linux. I did the npm install unoconv and thought that that would take care of installing the convert application, but only when I had installed it could I get it to run in Node.js sudo apt-get install unoconv
