"strict mode" doesn't get enabled for nodejs script when runing through forever

I have a script that uses strict mode, it’s an executable script with a “#!/usr/bin/node --harmony” shebang and runs fine when I directly call it from the terminal. I use this line at the start of the script to enable strict mode:

#!/usr/bin/node --harmony
"use strict";

However, if I run it through forever (forever start script_name) I obtain the following error in the logs that causes the script to abort over and over:

        let report = {
        ^^^
SyntaxError: Unexpected strict mode reserved word
  at Module._compile (module.js:439:25)
  at Object.Module._extensions..js (module.js:474:10)
  at Module.load (module.js:356:32)
  at Function.Module._load (module.js:312:12)
  at Function.Module.runMain (module.js:497:10)
  at startup (node.js:119:16)
  at node.js:906:3
error: Forever detected script exited with code: 8

Is there some way for me to indicate to forever that I want to run the nodejs script in strict mode? Or how can I specity commandline arguments for the node binary when running forever?

EDIT: I also tried doing this:

if(process.argv[2] == "start") {
    require("forever").start(__filename, {
           'uid': 'script_name',
           'minUptime': 500,
           'spinSleepTime': 0.5 * 60 * 1000,
           'command': 'node',
           'args': [ '--use_strict', '--harmony' ]
      });
}

This didn’t work either, I get the same result.

EDIT2: Funnily enough, I found it works when I use ‘perl’ as the command interpreter…

if(process.argv[2] == "start") {
    require("forever").start(__filename, {
           'uid': 'script_name',
           'minUptime': 500,
           'spinSleepTime': 0.5 * 60 * 1000,
           'command': 'perl'
      });
}

Looks like perl executes the file correctly after reading the shebang.

Yes. Either that or just do what most folks I know do and put "use strict" at the top of every one of your source code files.

I figured out the following incantation to make things work; This is working in production for the Heroku dashboard w/iojs:

"scripts": {
  "start": "node ./node_modules/.bin/forever -c 'node --use_strict --harmony_arrow_functions' --spinSleepTime 1 --minUptime 1000 ./bin/www"
}
