Updgrading systemjs to 0.20.x causes ./bin/tc to fail

I updated systemjs to =0.20.0:

  "dependencies": {
    "@types/webassembly-js-api.d.ts": "https://github.com/winksaville/webassembly-js-api.d.ts",
    "alsatian": "^1.3.0",
    "systemjs": "=0.20.0"
  },

And then reinstalled

$ npm install

Then rebuilt the compiler

$ npm run build

> turboscript@1.0.9-alpha build /home/wink/prgs/TurboScript.myfork
> tsc -p ./src && tsc lib/tc.ts

And then ran ./bin/tc and got the following error:

$ ./bin/tc -h

The same error happens on "systemjs": "^0.20.0" which get the latest version 0.20.12
