How do I fix "ReferenceError: System is not defined" when running script from command line?
<p>I'm trying to create typescript server side (example code <code>import mongoose from 'mongoose';
</code>) and I know I'm supposed to get systemjs initialized before, but I don't know how to in a server side script.</p>

<p>tsconfig.json</p>

<pre><code>{
  "compilerOptions": {
    "target": "es5",
    "module": "system",
    "moduleResolution": "node",
    "noImplicitAny": true,
    "removeComments": true,
    "preserveConstEnums": true,
    "sourceMap": true
  },
  "exclude": [
    "node_modules",
    "typings/main",
    "typings/main.d.ts"
  ]
}
</code></pre>
