Using createProgram outside node environment throws unhelpful exception message

When running createProgram from inside my angular app I'm thrown the 'ts.sys is undefined' error. This error is not helpful since I'm not given the reason for it. It took me a lot of time researching and eventually a question on SO (https://stackoverflow.com/questions/52969177/typescript-createprogram-throwing-ts-sys-is-undefined) to get the answer.

A more elaborate error message would've had been of great help.

TypeScript Version: 3.1.3

Search Terms: 'ts.sys is undefined'

Code

try {
    createProgram(Utils.getFileNames(), {
        lib: ['lib.es6.d.ts']
        // target: ScriptTarget.ES5,
        // module: ModuleKind.CommonJS
    });
} catch (ex) {
    debugger;
}

Expected behavior:

An exception message explaining I should run this code from node environment or pass my own compiler.

Actual behavior:

Throws 'ts.sys is undefined'

Comienza en la ruta de la API createProgram y reproduce la llamada mostrada desde un entorno Angular u otro entorno que no sea Node. Se considera completado cuando la excepción explica que el código debe ejecutarse en Node o recibir un compilador personalizado, en lugar de limitarse a informar de que ts.sys no está definido.
