I am encountering an issue while trying to utilize the createProgram function. The error message states that ts.sys is undefined when running the following code:
try {
createProgram(Utils.getFileNames(), {
lib: ['lib.es6.d.ts']
// target: ScriptTarget.ES5,
// module: ModuleKind.CommonJS
});
} catch (ex) {
debugger;
}
I have attempted both ways, with and without the commented part as well as including the lib option.
Below is the stack trace provided:

The code example I am using can be found on TypeScript's wiki page here: https://github.com/Microsoft/TypeScript/wiki/Using-the-Compiler-API#using-the-type-checker
I have researched this issue but could not find a solution. Could it be a missing package or configuration problem? Any assistance would be greatly appreciated...
Here are my imports:
import {
Node,
createProgram,
forEachChild,
isClassDeclaration,
isModuleDeclaration,
TypeChecker,
ScriptTarget,
ModuleKind
} from 'typescript';
