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?

Answer 1

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?

Answer 2

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);
