How do I debug “Error: spawn ENOENT” on node.js?

Question

When I get the following error:

events.js:72
        throw er; // Unhandled \'error\' event
              ^
Error: spawn ENOENT

Use require('child_process').exec instead of spawn for a more specific error message!

for example:

var exec = require('child_process').exec;
var commandStr = 'java -jar something.jar';

exec(commandStr, function(error, stdout, stderr) {
  if(error || stderr) console.log(error || stderr);
  else console.log(stdout);
});
